Solution
Short Answer P = 40 in
There are what looks like two parallel lines that are 7 inches long and two lines that are 13 inches long.
Perimeter = 2 * (Base + Slanted vertical lines that are parallel).
Perimeter = 2 * (7 + 13)
Perimeter = 2*20
Perimeter = 40 in
Area
Just in case you want it, the area is 11 * 7. The reason is that the height is perpendicular to the 7 in length.
