Answer:
34
Explanation:
First, we can construct an altitude from the edge of the like that says (5) and it will go up against the 11, creating a division in the big line. Since the altitude creates a right angle, a rectangle is formed, and so the top and bottom line is 5 units, and the sides are 8. Because of this, that means the rest of the 11 Unit line is 6 units. We can then bring the 8 as it is from the rectangle that we created, and we can create a Pythagorean triangle equation:
6^2 + 8^2 = x ^2
36 + 64 = x^2
X = 10
Now that we know the last side, add everything up to get the perimeter.
10 + 11 + 8 + 5 = 34
