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

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

Area = 1/2 × base × height.

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

Area = 1/2 × 10 cm × 5 cm

Area = 1/2 × 50 cm²

Area = 25 cm².

Thus, the area of the triangle is 25 cm², which is consistent with the calculation based on the provided base and height. The result indicates that the triangle's dimensions yield an area of 25 cm², confirming the correctness of the option.
