Question

Find the side length of a square with the given area. 121 in²

a. 11 in.
b. 60.5 in.
c. 1331 in.
d. 14,641 in

Answer 1

The area of a square is calculated using the formula s², where s is a side length of the square.

If we plug in our known quantities, we get the equation:

121 = s²

In order to get rid of the square, we must perform the inverse operation, which is to square root.

√121 = s

11 = s

Therefore, a side length of the square would be A. 11 in.
