Well, you could look Heron's formula, which works for any triangle, but you might have less work if you recognize that this is just a 3-4-5 right triangle scaled by a factor of 12.
So, the area is just 1/2 * 36 * 48 = 864
which is just the scaled version of 3-4-5:
12^2 * 1/2 * 3*4 = 864
find area of the triangle with the length of the side 36cm,48cm, and 60cm.
