Each side of a square is lengthened by 2 inches. the area of the new, larger square is 121 square inches. find the length of a s

tiny-mole [99]

Let the original side length be x. Then (x+2)^(in)^2 = 121 sq in.

Thus, x^2 + 4x + 4 = 121;
x^2 + 4x - 117 = 0 = (x-13)(x+9) = 0. Then x = 13 and x = -9.

We need to discard the negative result (-9).

The side of the original square is 9 inches. (answer)

Check: does (9+2)^2 = 121? Does 11^2 = 121? YES.
