Answer:
Step-by-step explanation:
Let the side of original square be x units
Then the area will be x × x = x^2 units
On increasing the s8de by 25%, the side become x + 25%of x
= x + 25x/100 = x +x/4
=5x/4
New area = 5x/4 × 5x/4
=25x^2//16 sq units
% increase in area =( 25x^2/16 - x^2)×
= (9x^/16) × 100 = x^2 (9/16 × 100)
= 0.5625 % ,of the original area
