Question

If side of a square is doubled, how many
times its area will be increased?​

Answer 1

Answer:

4 times

Step-by-step explanation:

Let the side of a square  = s m

Area  = s^2

now let side of the square = 2s

Area = (2s)^2 = 4s^2

ratio of the areas = s^2: 4s^2

= 1: 4

⇒ increases by 4 times
