Question

Find the change in% in area of a square if the side decrease by 1/2 times?

Answer 1

Answer:

75%

Step-by-step explanation:

let side be 2x

then area of square =(2x)²=4x²

now side decrease by 1/2 times, i. e. x

then new area will be (x)²

hence change = 4x²-x²=3x²

change%=(3x²/4x² )*100%= 75%
