The perimeter of the larger polygon is 120 yards.

The scale factor is 1/6.

The perimeter is proportional to the length of the sides, so if the smaller polygon has sides that are 1/6 of the corresponding sides in the larger polygon, then the perimeter is also 1/6 of the perimeter of the larger polygon:


P_s=(1)/(6)P_l=(1)/(6)\cdot120=20

The perimeter is scaled in the same proportion as the sides.

Answer: The perimeter of the other polygon is 20 yards.
