Question: 1 / 400

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

25

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

Area = (1/2) × base × height.

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 = (1/2) × 10 × 5 = (1/2) × 50 = 25 square units.

Therefore, the area of the triangle is 25 square units, which corresponds to the choice labeled as A. Understanding this formula is essential, as it effectively illustrates how both the base and height contribute to determining the overall area of a triangle.
