The length of the fence around the triangular section is 275m, one side is 86M

The length of the fence around the triangular section is 275m, one side is 86M, and the other is 5m longer than the first, find the length of its third side?

First, we calculate the length of the second side of the fence:
1) 86 m + 5 m = 91 m – becomes the 2nd side of the fence.
Next, we calculate how many meters the first and second sides of the fence occupy, adding together their two lengths:
2) 86 m + 91 = 177 m – occupy 1 and 2 sides together.
Next, let’s find out how many meters the third side of the fence takes, if we calculate the number of meters that the first and second sides take from the total number of meters.
3) 275 m – 177 m = 98 m – is the length of the 3rd side of the fence.
Total: 98 m.
