Answer:
A. 20.2 ft
Step-by-step explanation:
use the pythagorean theorem to get your answer.
a^2+b^2=c^2
17^2+11^2=c^2
289+121=410
***IMPORTANT, remember to square root the answer. 410 isn't your final answer, it's still in c^2 form. 20.2 is the correct answer after square rooting it. don't forget that for future problems

Hi!
Let's separate this shape into 3 smaller shapes. (see image)
Let's start with the green shape. The base is 5, and the height is 4.
5 x 4 = 20
Now the blue shape. The base is (15 - 5) 10, and the height is (3 + 4) 7.
10 x 7 = 70
Now finally, the red shape. The base is (15 - 12) 3, and the height is (11 - 4) 7.
7 x 3 x 0.5 = 10.5
Now add all of the areas together. 20 + 70 + 10.5 = 100.5
The answer is
100.5Hope this helps! :)
