When each side of a square was reduced by 2 metres, the area became 49 square metres. What was the length of a side of the original square?

Answer»

Let the length of each side of the original square be x, then

(x - 2)2 = 49

x - 2 = \(\pm\) 7

x - 2 = 7

x - 2 = -7

x = 7 + 2 = 9

x = -7 + 2 = -5

The length of each side of the original square = 9 cm
