Find the area of a triangle with base 8 and height 5.

Explanation:
The key idea is that the area of a triangle is found by taking base times height and then dividing by 2. This division by 2 reflects that a triangle with the same base and height as a rectangle has half the area. With a base of 8 and a height of 5, multiply 8 by 5 to get 40. Then divide by 2 to get 20. So the area is 20 square units.
