Answer:
The answer is C. 72
Step-by-step explanation:
First you'll have to find what the unknown sides are? Basically you just subtract 17 inches with 10 inches to get 7 inches for the unknown horizontal line, and for the unknown vertical line you subtract 19 inches with 11 inches to get 8 inches. After that you add all the side up to 72 inches in total. Hopefully this helps.
