    You can find the area using Heron's formula.

    A=√ (s (s-a) (s-b) (s-c)),

    where a, b, c are sides of the triangle,

    and s = (a+b+c) / 2 - half perimeter of a triangle.

    a=15,

    b=15

    c=18

    s = (15+15+18) / 2=48/2=24

    s=24

    s-a=24-15=9

    s-b=24-15=9

    s-c=24-18=6

    A=√ (24*9*9*6) = √ (4*6*6*9*9) = 2*6*9=108

    A=108
