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
