A rectangle is one-fifth as tall as it is long. If its height is reduced to one-half of its current height, what is the ratio of the new rectangle's perimeter to the original rectangle's perimeter?

Question

Lets say the original rectangle has the dimensions 1 by 5.
perimeter = 12
cut the height in half so you get 1/2
new dimensions are 1/2 by 5
new perimeter = 11

--> ratio = 11:12
