The sides of a triangular lot are represented by x, 2x, and 3x + 2. Find each side if the perimeter is 362 feet.

  • math -

    To find perimeter, you add up all the sides.

    So, your equation would be:
    x+2x+3x+2=362

    Combine like terms:
    6x+2=362

    Solve to get x by itself by subtracting 2.

    6x=360

    Divide by 6

    x=6

    To find each side, substitute 6 in for x for each of the expressions, x, 2x, and 3x+2

    Side one would be 6 feet
    Side two would be 12 feet because 6(2) is 12
    Side three would be 20 feet because 6(3) is 18 and adding 2 would give you 20.

  • math -

    O my, x=60, not 6.. My fault for overlooking that.

    The three sides would be,
    60
    120
    182

    *Sorry again
