Solution 1

To find the area of a triangle when two sides and the included angle are given, we can use the formula:

Area = 1/2 * a * c * sin(B)

where: a and c are the lengths of two sides of the triangle, B is the angle included between the two sides.

Given in the problem: a = 20 c = 16 B = 115°
