ANSWERS: __9__ square inches

(1) A = 3 feet x 3 feet

or

(2) A = 3 feet x 3 feet

A = 9 square feet

A = 36 inches x 36 inches

A = 1,296 square inches

(Look up square inches in conversion table.)

A = 9 square feet x 144 (inches in 1 square foot)

A = 1,296 square inches

SOLVING FOR LENGTH AND WIDTH

The formula A = L x W can be expressed in two other ways:

(1) If the area and width are known and you want to solve for the length.

Length = Area__, or Length = Area + Width

Width

L= A__

W

(2) If the length and area are known and you want to find the width.

Length = Area__, or Width = Area + Length

Length

Width = Area__

Length

Solve: What is the length of a field if the area is 760 square feet and the
