Explanation

Go back

The area of a triangle is equal to one-half the product of the base and the height, so you can use that formula to find the area:

Area = 1/2 * Base * Height

Area = 1/2 * 20 * 15

Area = 1/2 * 300

Area = 150

So the area of the triangle is 150 square units.

Area = 1/2 * Base * Height

Area = 1/2 * 20 * 15

Area = 1/2 * 300

Area = 150

So the area of the triangle is 150 square units.
