Question
When the side of a square is increased by 50%, then what
will be the %Â change in the area of the square?Solution
Let the side of a square be=10s Then old side of the square is =10s x 10s = 100s2 Then, New side of the square will be = 15s x 15s = 225s2 Therefore, required % change will be = 125 x (100/100) = 125
