Question

The perimeter of a triangle is 117in. The lengths of the sides are represented by consecutive integers. Find the lengths of the sides

Answer 1

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
