Answer:

first take common

2(a+b)=c2

a+b=c

so,

if tha value of a+b is c

then

2(a+b)=c2

2×c=c2

c2=c2

proved

100 and 400 would be your side lengths

100^2 + 400^2 = c^2

10,000 + 160,000 = c^2

170,000 = c^2

take square root of both sides

the answer would be about 412.3 but the exact answer is 412.31056

hope this helps
