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

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 cm, and the height is 5 cm. Substituting 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, which corresponds to the correct answer. This calculation demonstrates how the formula applies directly to determine the area using given dimensions. Understanding the process helps reinforce the concept of area, ensuring that you can apply it in various geometric contexts.
