What is the perimeter of this shape?
Fudgin [204]

Answer:

87 feet

Step-by-step explanation:

Two of the sides here are unknown. The one on the leftmost side is equal to 9, since on the other side it also has a length of 9 feet. The section on the top right has a length of 30-9-9=12 units. Adding all of these values together now, you get a total perimeter of:

30+9+12+9+9+9+9=87 feet

Hope this helps!
