Answer:

Let the side of the given square be x, then its area is x^2.

When the side is decreased by 20%, new side is x(100–20)/100=x*80/100=0.8x

Area of the new square=(0.8x)^2= 0.64x^2

Difference in areas is =x^2–0.64x^2=0.36x^2

Percentage decrease =(0.36x^2/x^2)*100=0.36*100=36%

I hope it help ya. Have a good day/night ahead dear~
