day one

1) Finding the area for a rectangle.

Area=LxW

Area=3x7

Area=21

2.)Finding the area for a triangle.

Area=1/2 BxH

Area=1/2 4x5

Area=10

3.)The relashionship between the triangle and the rectangle is that the triangle is half of the rectangle.

4.) I have number four done, I just dont know how to put the pictures on blogger.

5.) You would find the area by measuring the the LxW. Basically however you measure triangles and rectangles is how you would find the answer. (have picture just don't know how to put it on blogger)

6.)To calculate the area a 3D shape you need to first add the sides together to get a number then you multilpy that to get you answer then you just add all you final numbers to get you final answer. Yes there is a shot cut you just multipy everthing by two .

(i think not positive)

7.)To find the answer for number 7 all you have to do is follow the same rules for what you did for number 6. (i think not sure though)

Area=LxW

Area=3x7

Area=21

area= WxL

area= 3x5

area= 15

to find an area of a triangle you have to multiply the height and the base. You have to find the

right angle to find it's height. When it's multiplied it needs to be divided by two.

area= 1/2 HxB

area= 1/2 3x5

area= 1/2 15

area=7.5

the relationship between a triangle and a retangle is that the triangle is half of a rectangle.

(most of the time that is...)

thats all for now. until i find out what to do next.

day 1

Day 2

1 way is to calculate the area of each rectangle

Rectangle 1 Rectangle 2

A=lxw A=lxw

A=10x 3 A=8x3

A=30 cm squared A= 24cm squared

TSA= 30+24=54

the other way is to find the perimeter of the full rectangle and subtract the remainder that you don't use

Day3

You can cut of the end which is a right angle triangle and add it to the other side

Then you are simply finding the area of a rectangle

Day 4

O.K. There are 2-3 different sized sides. Assuming that there are 3 different sizes, find the area of one of each, multiply it by 2 and add them together. You can also multiply length, width, and depth to get the TSA(total surface area)

Triangular Prism Question

To solve each triangles area

The first part is that both triangle have the same are. The base is 4cm and the height is 5cm. Usually it is b x h/2, but since both triangles combine to create one rectangle, the formula is just b x h

A=bxh

A=4x5

A=20cm squared

All of the rectangles have different areas. The common one is 10.

First rectangle

A=lxw

A=10x4

A=40cm squared

Second Rectangle

A=lxw

A=10x5

A=50 cm squared

Final rectangle

A=lxw

A=6x10

A=60cm squared

To find the total surface area, we add it all up

20+40+50+60=170 cm squared

170 cm squared is the total surface area!! HOORAY!

Here's my own t. prism

Well, here's the circle part

First of all, your circle's radius must be the same length as the side length of the square

Let's say that the radius is 4 ( just like today)

The side length of the square would be four. to find the area of the square is to well, square the length i.e. multiply it by itself

A=s squared

A=4 squared

A=16 cm squared. THis is the same thing as squaring the radius of the circle. all that would be left to do would be to multiply the area of the square by Pi (3.1415...something or other )

answers to bonus Q's qre in the comments thingy where the Q's are, harbeck

IT'S NOW IN PICTURES!!!!

The rectangle is twice the size of the triangle.

A=LxW

A=5x4

A=20

To find the area of the triangle you have to:

A=1/2 BxH

A=1/2 5x4

A=1/2 20

A=10

The relationship between a rectangle and a triangle is that a triangle is half of a rectangle.

I couldn't get my pictures in.

w = 5m L=2m

finding the area...

area= 5xW

area =5x2

area= 10**2. The area of a triangle is found by multiplying its height by its base. To find the height of a triangle look for a right angle. Once you multiply the base and height you divide the total by 2. The formula looks like this:**

Base=6

Height=12

finding the area..

Area=BxW÷2

Area=72÷2

Area=36**The relationship between the area of a triangle and the area of a rectangle is that every triangle is half of a rectangle.****-****4.Complex Figures****5. To find the area of a parallelogram you need to find the height and multiply it by the base. this is different than a rectangle. In a rectangle you have the height and base (due to the right angles in each corner). You multiply length times width. Here are three pictures that shows the relationship between the rectangle and parallelogram.****6. Surface Area is when you have to calculate the area of all the sides of a 3D Shape. Choose a rectangular solid (aka box of somekind) and show how to calculate its Surface Area. Are There any shortcuts??**

**7. This triangle has side lenghts of 4 cm, 5 cm, and 6 cm. Create a triangular prism that has a depth of 10 cm. What is its surface area.?**

1.Area of a rectangle:

A=L(W)** **

**A=4(6)****A=12**

2.Area of a triangle:

A=b(h)/2

A=3(2)/2

A=3

3.The relation ship is that a triangle can be half of a rectangle.

4.Complex Figures5.To find the area of a parallelogram you need to find the height and multiply it by the base. This is different than a rectangle. In a rectangle you have the height and base *due to the right angles in each corner*. You multiply lenght times width. Here are three pictures that shows the relationship between the rectangle and parallelogram.
