Assuming the "length" mentioned in the problem refers to the length of the triangle's side opposite to the height:

Area of triangle = (base x height) / 2

Let the length of the side opposite to the height be L.

Then, the base of the triangle would be 1/2 * L.

Substituting the values given in the problem:

Area of triangle = (1/2 * L * 24) / 2

= (L * 12) / 2

= 6L

Therefore, the area of the triangle is 6 times the length of its opposite side (in square cm).
