You use Pythagorean theorem to solve this problem.a^2+b^2=c^2
A.53*53=45*45+28*28
2809=2025+784
2809=2809

B.85*85=13*13+84*84
7725=169+7056
7725=7725
C.85*85=36*36+77*77
7725=1296+5929
7725=7725
D.65*65=16*16+61*61
4225=256+3721
4225=3977

The answer is D

Number 15 is C.52 ft

Explanation: You have to use the pythagorean theorem to find side c which would be the diagonal fence.

a^2+b^2=c^2
20^2+48^2=c^2
400+2304=c^2
2704=c^2
√2704=√c
52=c

2/5 can be simplified to 8/20

1/4 can be simplified to 5/20

8/20 + 5/20 = 13/20

I cannot be simplified anymore
