Xavier is building a triangular fence. The length of the second side will be 1 foot longer than the length of the first side. The length of the third side will be 1 foot longer than the length of the second side. The total perimeter of the triangle will be 63 feet. What will the length of the third side be?

22 feet

Step-by-step explanation:

Let the length of the first side= x foot

The length of the second side will be 1 foot longer than the length of the first side.

The length of the third side will be 1 foot longer than the length of the second side.

Perimeter of the triangle = 63 feet

Adding the length of the sides

x+x+1+x+2=63

3x+3=63

3x=63-3

3x=60

x=20 feet

Therefore, the length of the third side = 20+2=22 feet
