One side of a triangle is three times the shortest side. The third side is 7 feet more than the shortest side. The perimeter is 62 feet. Find all three sides.

  • begining algebra -

    side 1= 3x
    side 2= x
    side 3= x+7

    3x + x + x+7 = 62
    5x = 55
    x=11

    side 1= 3(11) = 33
    side 2= (11) = 11
    side 3= (11)+7 = 18
