The area of a square with sides of length s given by s^2. The area of a square is 49 square inches. What is the length of one side of the square?

Question

Round to the nearest hundredth if necessary.

Answer 1

S^2 means s x s. So, your equation is s x s = 49. If you know your times tables, you know that 7 x 7 = 49. If you don't know your times tables (or when these get harder and you have bigger numbers), a calculator has a square root key, which look something like this: √ . That will tell you what number is multiplied by itself to get another number, in this case 49. Either way, the answer is 7 inches.
