    17 cm

    Step-by-step explanation:

    P = a+b+c

    Perimeter is sum of sides

    49 = 14+18+x

    x = 49 - 32 = 17 cm

    The third side is 17 cm

    17

    Step-by-step explanation:

    First side+second side+third side=perimeter

    14+18+third side=49

    32+third side=49

    Subtract 32

    third side=17
