Question

when each side of a square was reduced by 2 meters,its area became 49sq.what was the side of the first square?​

Answer 1

Answer:

Length of each side of first square = 9m

Step-by-step explanation:

Let initial length of each side be x m

Initial area of square = x^2 sq. m

New length of each side = (x - 2) m

New area of square = (x-2)^2 sq.m

Now, new area of square = 49 sq. m (Given)

Hence-

(x-2)^2 = 49

(x-2) = √49

x - 2 = 7

x = 7 + 2

x = 9 m

Therefore, Length of each side of first square = 9m
