Question

The shortest sides of two similar polygons have lengths in the ratio 2:5, the perimeter of the smaller polygon is 20, the perimeter of the larger polygon is _____

Answer 1

the ratio is----- >2:5

let
x=perimeter of the smaller polygon=20
y=perimeter of the larger polygon

therefore
(2/5)=(x/y)-------- > (2/5)=(20/y)----------- > y=20*5/2=50

the answer is
the perimeter of the larger polygon is 50
