Question

How many square inches, 1 in. by 1 in., fit in an area if 1 square foot, 1 ft by 1 ft?

Answer 1

We have the following:

We must convert square feet to square inches

We have that 1 foot is equal to 12 inches

`1ft^2\cdot((12in)^2)/((1ft)^2)=144in^2`

Which means that one square foot equals 144 square inches.
