Question

if the side of square is increased by 50%,find the percent increase in its area

Answer 1

Answer:

Step-by-step explanation:

Let the side be x

Therefore 50% of x = 50/100 × x= x/2

x +x/2 =3x/2

Earlier Area =x^2

New area =9x^2/4

9x^2/4 -x^2

5x^2/4 = 1.25x^2

Y% of x^2=5x^2/4

Y/100×x^2=5x^2/4

Y = 5×25

Y=125%
