Question: 1 / 400

What is the formula for finding the area of a triangle?

Area = base × height

Area = length × width

Area = 1/2 × base × height

The formula for finding the area of a triangle is correctly identified as 1/2 × base × height. This formula stems from the concept that a triangle can be understood as half of a rectangle when considering the same base and height measurements.

In this formula, the base represents one side of the triangle, and the height is the perpendicular distance from that base to the opposite vertex. By multiplying the base and height, you calculate the area of the rectangle that would encompass the triangle. Since a triangle occupies exactly half of that rectangle, you divide the product of base and height by 2, leading to the final formula.

This approach provides a simple yet accurate method to calculate the area of any triangle, regardless of its type, which is why this formulation is universally taught in mathematics.
