Problema Solution
Corresponding sides of two squares are in the ratio of 13 to 19. What is the ratio of their perimeters?
Answer provided by our tutors
let
a = the side of the first square then its perimeter is 4*a
b = the side of the second square then its perimeter is 4*b
we know that a : b = 13 : 19
4a : 4b = (4a)/(4b) = a/b = a : b = 13 : 19
the ratio of their perimeters is 13 : 19.
