Answer:
82 inches
Step-by-step explanation:
This shape can be divided, forming 3 rectangles. Now this will be even easier to find the perimeter of this polygon.
A perimeter is found by adding all the sides of a shape
( length + length + width + width )
Rectangle 1 = 7 + 7 + 3 + 3 = 20 inches
Rectangle 2 = 17 + 17 + 2 + 2 = 38 inches
Rectangle 3 = 9 + 9 + 3 + 3 = 24 inches
Total Perimeter = 20 + 38 + 24 = 82 inches
