How can you find the area of an irregular polygon (one that isn't a rectangle or triangle)?

Divide the polygon into shapes that you know how to find the area of (rectangles and triangles). Find the area of each individual shape and add the areas up to find the total area. DECOMPOSE.

Or, you can make the shape into one you know a formula for, then subtract what you don't need.

200

a triangle has a base of 10 and a height of 16, a parallelogram has a base of 10 and a height of 16. Which one has the larger area? How do you know?

The parallelogram has the larger area because to find the area you would do A=bh, so A=10x16. For the triangle, you would do A=bh/2, so A=10x16/2. The triangle's area would be half the size of the parallelogram

Why is it so important to attend to precision when plotting points so you can find the perimeter of a polygon on a coordinate plane?

If you incorrectly plot a point, your perimeter will be off because you won't make the exact shape you are supposed to plot.

What is scale factor? Give an example of a problem that would ask you to use scale factor. 

Scale factor is the amount each unit on the coordinate grid represents.
