What is the area of a triangle with a base of 5 and a height of 3?

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

Area = (base × height) / 2.

In this case, the base of the triangle is given as 5, and the height is 3. Plugging these values into the formula gives:

Area = (5 × 3) / 2

= 15 / 2

= 7.5.

Therefore, the area of the triangle is 7.5, confirming that the selected answer is correct. This formula is essential for determining the area of triangles, as it accounts for how the dimensions of the base and height relate to the overall size of the triangle.
