What is the area of a triangle with base 12 units and height 9 units?

Explanation:
The area of a triangle is half the product of its base and its height. With a base of 12 units and a height of 9 units, multiply 12 by 9 to get 108, then divide by 2 to get 54. So the area is 54 square units. The other numbers would come from using different heights—for example, a height of 8 gives 48, a height of 10 gives 60—but for this base-height pair, 54 is the correct area.
