Question

Explain how to use a coordinate plane to find the area of a rectangle with vertices (–4, 9), (–4, –3), (–1, –3), and

(–1, 9). What is the area?
sample response, please?

Answer 1

-36 is the area

Hope this helps!

Answer 2

The area of rectangle can be found by multiplying the width and length of the rectangle. To find the length of the rectangle compare the x values of two of the coordinates: Since the length is . To find the width of the rectangle we need to look at the y coordinates of two of the points.
