What is the area of this triangle on the bottom base? It’s 8 inches and on the left side. The length is 10 inches so what is the area?

To find the area of a triangle, you can use the formula:

Area = 1/2 * base * height

In this case, the base is 8 inches and the height (or the length of the left side) is 10 inches.

Area = 1/2 * 8 * 10
Area = 40 square inches

Therefore, the area of the triangle on the bottom base is 40 square inches.
