The shortest side of two polygons have lenghts in the ratio 2:5.The perimeter of the smallest polygon is 20. what is the perimeter of the large polygon?

This can only be answered if the two polygons are similar, so I will assume they are
then if P is the perimeter of the larger
P/20 = 5/2
P = (5/2)(20) = 50
