Answer:
52 in
Explanation:
I added all the sides I already know which is 10+5+5+16= 36
then to find the sides we don't know I subtracted part of the side we do know from the full side we do know for example I subtracted 5 from 10 and 5 from 16 to get 5 and 11 as the missing sides then I added those to the 36 so final answer is 52 in
