    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.

    Therefore, length of the second side = (x+1) foot

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

    Therefore, length of the third side = (x+1+1) = (x+2) foot

    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
