Question

what happens to the area of a square is douled​

Answer 1

Case (1st)

if the length of side is doubled

=> side of square =2a

And

Area = (2a)² = 4a²

that means ...

Area become four times of Area when length of side is doubled.

Case (2nd)

if length of side is tripled

=> side = 3a

=> Area of square = (3a)² = 9a²

that means..

Area become 9 times when side of square is tripled.

Case(3rd)

if length of side is halved

=> side = a /2

=> Area of square = (a/2)² = a²/4

that means..

Area become one-fourth when side of square is halved

Answer 2

2*side*side is it right
