Answer:

  • 48 units

Step-by-step explanation:

Perimeter is the sum of the side lengths

If polygon A has perimeter

  • P  = a+b+c+d for example

Then polygon B has perimeter of

  • P' = 1/3a+1/3b+1/3+1/3d = 1/3P as each side is 3 times smaller than the corresponding side

Since P = 144

  • P' = 1/3P = 1/3*144 = 48 units

We can write a ratio comparing the sides of both polygons.

A:B = 3:1

Since we know that 144 is the perimeter for polygon A, we can substitute it.

144:B = 3:1

~Simplify

144 = 3B

Divide 3 to both sides

48 = B

Therefore, the perimeter of B is 48 units.

Best of Luck!
