, what happens to the area of a square when(a) Its side is doubled ?(b) Its side is trippled ?(c) Its side is halved?

Answer»

Case (1st)if the length of side is doubled=> side of square =2aAndArea = (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.
