What is the area of a triangle with a base of 10 and a height of 5?

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

Area = (base × height) / 2.

In this case, the base of the triangle is 10 units and the height is 5 units. Plugging these values into the formula gives:

Area = (10 × 5) / 2 Area = 50 / 2 Area = 25 square units.

Therefore, the area of the triangle is 25, making this the correct answer. This calculation demonstrates how the area is derived from the two dimensions specified, reinforcing the basic principles of geometry related to triangles.
