.
M=length of middle side; S=length of short side=M-79mi; L=longest side=M+377mi
Perimeter=S+M+L
3082mi=(M-79mi)+M+(M+377mi)
3082mi=3M+298mi
2784mi=3M
928mi=M ANSWER 1: The length of the middle side is 928 miles.
S=M-79mi=928mi-79mi=849mi ANSWER 2: The short side is 849 miles,
L=M+377mi=928mi+377mi=1305mi ANSWER 3: The long side is 1305 miles
.
CHECK:
.
Perimeter=S+M+L
3082 mi=849mi+928mi+1305mi
3082mi=3082mi
