Question

A square patio has an area of 143 square feet. How long is each side of the patio to the nearest tenth?

Answer 1

Since all the sides of a square are the same, all we need to do is take the square root of the area.

√143 = 11.958260...

How to round:

5 and above, round up

4 and below, round down

11.958260... -> 12

Therefore, the side lengths of the square is aproximately 12 feet.

Best of Luck!
