What is the area of the triangle? Length 15 and width 2.5

The area of a triangle is given by the formula:

Area = 0.5 * Base * Height

In this case, the base (length) is 15 and the height (width) is 2.5. Plug these values into the formula to calculate the area:

Area = 0.5 * 15 * 2.5
Area = 0.5 * 37.5
Area = 18.75

Therefore, the area of the triangle is 18.75 square units.
