Question

if the each side of a square is increased by 50% then by how much percent will its area be increased?

Answer 1

in a square all side r equal right so if increase each side 50% then area will increase equal

Answer 2

Let the side of the square be x
Area of thesquare =x^2
50% of the side=x/2
New side=x+x/2=3x/2
Area of the square with a new side=3x/2^2=9x^2/4
Increased %=increased area/actual area×100
increased area=(9x^2/4)-x^2=5x^2/4
increased %={(5x^2/4)/x^2}×100=125%
