Question

Suppose you transform a square by increasing one side by 12 units and decreasing the other side by 8 units. If the area of the resulting rectangle equals 44 how many units long was the side of the original square?

Answer 1

(x+12)(x-8) =44

x^2 +4x - 96 =44

x^2 +4x -140 =0

(x+14)(x-10) =0

x = 10 (ignore the negative solution)

square was 10 x 10.

then transformed to a rectangle 22 x 2 = 44 for area
