Kim's Geometry post

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 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 lenght times width. Here are three pictures that shows the relationship between the rectangle and parallelogram.


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.?
