Please select the best answer and click \"submit\". Polygon X is similar to polygon Y. Polygon X is 1/3 the size of polygon Y. The perimeter of polygon X is 81. What is the perimeter of polygon Y? A. 81 B. 9 C. 27 D. 243

Solution

Given polygon-X is similar to polygon-Y,

So, the number of sides in both polygons is same.

Let, side of polygon-X & polygon-Y are \'a\' units & \'b\' units. Given

a=(1/3)b and Perimeter of polygon-X is 81.

i.e., na = 81 (where n is the number of sides.)

perimeter of polygon-Y = nb = n(3a) = 3(81) =243
