Its area becomes 3 times greater, and perimeter becomes 6 times greater

Answer 1

area becomes 3 times greater because you're enlarging the dimention by 3 ea.
So, B X H = A(original)
B X 3 H = 3A

Answer 2

oh wait do you mean ALL the sides or just one pair?

Answer 3

if you mean all the sides, then its 9 times greater because
3B X 3H = 9A

B= base(one pair of sides)
H=height(other pair of sides)
A= area
