The side of a square is 5cm. How many times does the area increase, if the side of the square is doubled?

Question

Philoid · Accepted Answer

Side of square = 5 cm

Area of square = 5 × 5

= 25 sq.m

If side doubles = 10 cm

New area = 10 × 10

= 100 sq.m

So the area becomes four times the old area.
