Question

Toni is designing a rug using a coordinate plan. She uses polygon A B C D with vertices A (2, 2), B (-2, 2), C (-2, -2), and D (2, -2). Each unit on the grid represents 1 foot. What is the area of the actual rug?

Answer 1

1. Plot the points in the x-y axis. Check the picture

2. The figure formed is a square, so the area is 4*4= $4^{2}$=16 (ft square)

3. We can also count the 1 $ft^{2}$ squares, there are 16 of them.
