The area of a rectangle is 63 ft2. If the rectangle is 9 feet long. What is it's width

7 feet.

The area of a rectangle is equal to its length times its height.

In this case, the area can be represented by 63 = 9 * w.

Divide both sides of the equation by 9 to get 7 = w.

This means the width is 7 feet.

Divide the area with the length (9 feet long)

Area: 63/9

= 7 feet long

7*9=63 ft 2

Answer: 7 feet long
