The two legs of a right-angled triangle are 15 and 4. Find its area.

Since the triangle is rectangular, its area can be found by the formula S = 0.5ab, where a and b are the legs of the triangle.
In our case, the legs are a = 4, b = 15.
S = 0.5 * 4 * 15;
S = 0.5 * 60;
S = 30.
Answer: The area of a triangle is 30 square units.
