Question

if each side of a square is increased by 20% then it's area will be increased by ? ( step by step explanation)​

Answer 1

Answer:

12⅓ because I guess this one from myself

Answer 2

Answer:

let side be x

so area of square is x²

Now,

new side is x+20% of x

= 6x/5

new area = 36x²/25

so increase in area

(36x²-25x²)/25

= 11x²/25

increase in area= 11x²/25 × 1/x² × 100%

=44%
