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, 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 the values into the formula gives:

Area = (10 cm × 5 cm) / 2 = 50 cm² / 2 = 25 cm².

Thus, the area of the triangle is 25 cm². This means that the correct answer is the one that reflects this calculated area. It is important to use the correct dimensions and the formula appropriately to accurately determine the area of any triangle.
