Question

If the area of a square is 169 square units, what is the length of the side of the square?

Answer 1

Let's call the side of the square "s". The area of a square is found by multiplying the side length by itself, so the equation would be s * s = 169. To find the square root of 169, the side length of the square, we have to take the square root of both numbers. The square root(s²) = sqrt(169). The square root of 169 is 13 (13 x 13 = 169). Therefore, the length of the side of the square is 13 units.
