STEP 1:
Determine length of all sides. There are 6 sides to this shape.
Sides:
11 in
19 in
18 in
10 in
For the last two, subtract the length of the short side, from the length of the longest side.
(18 in right side - 11 in left side)= 7 in - top center down
(19 in bottom - 10 in top)= 9 in - top left across
STEP 2:
Perimeter= add length of each side
P= 11 + 19 + 18 + 10 + 7 + 9
P= 74 inches
ANSWER: C) 74 inches
Hope this helps! :)
