Answer:

Perimeter of polygon B = 80 units

Explanation:

Since both polygons are similar, their corresponding sides and perimeters are proportional. Knowing this we can setup a proportion to find the perimeter of polygon B.


(side-polygonA)/(side-polygonB) =(perimeter-polygonA)/(perimeter-polygonB)

Let
x be the perimeter of polygon B. We know from our problem that the side of polygon A is 24, the side of polygon B is 15, and the perimeter of polygon A is 128.

Let's replace those value sin our proportion and solve for
x:


(side-polygonA)/(side-polygonB) =(perimeter-polygonA)/(perimeter-polygonB)


(24)/(15) =(128)/(x)


x=(128*15)/(24)


x=(1920)/(24)


x=80

We can conclude that the perimeter of polygon B is 80 units.
