20 units

Answer 1

The area formula for a triangle is A = 1/2 * base * height.

Triangle C can be decomposed into two right triangles with heights 4 units and 5 units. The base is 8 units.

So, the total area of Triangle C is A = (1/2) * 8 * 4 + (1/2) * 8 * 5 = 20 units.

Therefore, the area of Triangle C is 20 square units.
