Let the sides of square be x
After increasing by 25% new side will be=x+(25/100*x)
x +x/4=5x/4
So new side will be=5x/4
Area before incresing the side=xsquare
After increasing=(5x/4)2=25x/16square
Increase in area=25x/16-x=9x/16
Inceasre%=9x/16/x*100=56.25%
So area will increase by 56.25%
After increasing by 25% new side will be=x+(25/100*x)
x +x/4=5x/4
So new side will be=5x/4
Area before incresing the side=xsquare
After increasing=(5x/4)2=25x/16square
Increase in area=25x/16-x=9x/16
Inceasre%=9x/16/x*100=56.25%
So area will increase by 56.25%
