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?
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.
