The perimeter is 117in. The sides are consecutive integers. By the picture, we can see that one of the sides is x.
Step 1: Naming the sides
The sides are going to be x, x+1 and x+2, as the answer says they're consecutive integers.
Step 2: Finding the sides
Adding the 3 sides will allow us to finbd them, as we know the perimeter:
x+x+1+x+2=117
3x+3=117
3x=117-3
3x=114
x=38
So, the sides are:
38in, 39i and 40 in
