58%
Correct Answer
C
56.25%
Your Answer
D
> 60%

Solution

The correct option is D 56.25%

Let the side be 10 cm. Then the area will be  100cm2

New side  =125% of 10=12.5cm;

Area=(12.5)2=156.25

Percentage increase in area =56.25%.

Alternatively: If x is the percentage increase in the side of a square, then increase in area is given by

x+x+x×x100=2x+x2100=25+25+25×25100=56.25%
