L=longest side; S=Second side=(1/3)L; T=Third side=L-10ft
.
L+S+T=102
L+(1/3)L+L-10ft=102
(7/3)L=112
7L=336
L=336/7
L=48
ANSWER 1: The longest side is 48.
.
S=(1/3)L=(1/3)(48)=16
ANSWER 2: The second side is 16.
.
T=L-10ft=48-10ft=38
ANSWER 3: The third side is 38.
.
CHECK:
L+S+T+102
48+16+38=102
102=102
