Question

If the side of a square is increased to three times the original size, the new area of the square will be ____ times the original area.

• A. 9

Answer 1

The correct option is A 9
Original area of the square = side $\times$ side

New side of the square = 3 $\times$ side
New area of the square
= (3 $\times$ side) $\times$ (3 $\times$ side)
= 9 $\times$ side $\times$ side

So, we see that the new area of the square will be 9 times the original area.
