find area of the triangle with the length of the side 36cm,48cm, and 60cm.

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 345 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 345:
12^2 * 1/2 * 3*4 = 864
