Question

If the length of side of a square is reduced by 50 percent then find the percentage decrease in The area?​

Answer 1

Answer:

75%

Explanation:

Let the side of square =a

Area of square=a²

Now the side is =a/2

Change in area=a²-a²/4=3a²/4

Percent of change in area=[(3a²/4a²)*100]%=75%
