Question

How much will you increase the side of the square to increase the area of a square
by nine times?​

Answer 1

Answer:

3 times is your answer.

Example:

S1 = 2 units

A1 = 2*2 = 4 units

9 times the area =  4*9

                           = 36

A2 = 36 units

S2 = root 36

    = 6 units

6/2 = 3

Therefore, the side has to be increased by 3 times.
