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

• A. Area = base × height
• B. Area = ½ × base × height
• C. Area = base + height
• D. Area = base - height

Answer: (B)

The formula for finding the area of a triangle is accurately stated as the product of the base and the height divided by two, represented as Area = ½ × base × height. This formula derives from the concept that a triangle can be thought of as half of a parallelogram. To derive this, consider a parallelogram: the area is calculated by multiplying the base by the height. Since a triangle occupies exactly half of the space of a parallelogram with the same base and height, the area is thus halved, leading to the final formula. This relationship emphasizes the importance of both the base (the length of one side of the triangle) and the height (the perpendicular distance from the base to the opposite vertex) in determining the area. Using the correct formula allows for accurate calculations in various applications, including aviation maintenance, where precise measurements are crucial.
