Solution:
Note that:
- Formula of the area of triangle = ½ × b × h
- 13 cm = Base
It should be noted that one leg of the right triangle is 8 cm. Let's use 8 cm as the altitude of the triangle.
Finding the area of the triangle:
- ½ × 13 x 8
- => ½ × 104
- => 52 cm²
Looking at the options, we can conclude that Option A is correct.
