If a triangle has a base of 10 cm and a height of 5 cm, what is its area?

To determine the area of a triangle, the formula used is:

Area = (base × height) / 2

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

Area = (10 cm × 5 cm) / 2

Area = 50 cm² / 2

Area = 25 cm²

Thus, the area of the triangle is 25 cm², making that answer the correct choice. This formula applies universally to all triangles, regardless of their specific shape, provided the base and height are correctly identified. In scenarios where the dimensions change, simply apply the same formula with the new values to find the area accurately.
