Question

A rectangle has a width of 5 meters and length of 14 meters. If a similar rectangle has a width of 15 meters, what's its perimeter, in meters?

Answer 1

sides must be in the same ratio, thus the perimeter is in the same ratio

ratio of sides = 15/5 = 3:1
perimeter of original = 38

so perimeter of new one = 3(38) = 114
