Let the shortest side be x.
one side is 13 more than the shortest = x + 13
Longest is 31 more than the shortest = x + 31
Perimeter of triangle = 140
x + x + 13 + x + 31 = 140
3x + 44 = 140
3x = 140 - 44
3x = 96
x = 96/3
x = 32
Shortest side, x = 32
Other side = x + 13 = 32 + 13 = 45
Longest side = x + 31 = 63
Side 1 = 32 inches
Side 2 = 45 inches
Side 3 = 63 inches
I hope this helped.
