An artist paints a mural that is 3 feet

long and 5 feet wide. She paints a

second mural that is 5 feet long and 5

feet wide. A third mural is 7 feet long

and 5 feet wide. Explain how the areas

of the murals change.

Each area will be different every time because the length and the width will be different

The area of a square or rectangle is length * width. It changes because the answers to the multiplication problems are different. 3 * 5 = 15, while 5 * 5 = 25. Because one of the numbers you have to multiply are different in each problem, you'll have a different answer each time.
