What formula is used to find the area of a trapezoid?

• A. A = 1/2 H (base1 + base2)
• B. A = B × H
• C. A = b × h
• D. A = 2 × (base1 + base2)

Answer: (A)

The formula for finding the area of a trapezoid is derived from the fact that a trapezoid has two parallel sides, referred to as the bases. The formula, A = 1/2 H (base1 + base2), effectively reflects the average length of the two bases multiplied by the height of the trapezoid. The height (H) serves as the perpendicular distance between the two bases, ensuring that the area calculation accurately represents the enclosed space. Using this formula, you take the sum of the lengths of the two bases, divide that sum by two to find the average length, and then multiply by the height to find the total area. This allows for an accurate and straightforward method of calculating the area of trapezoidal shapes, which is particularly useful in geometry. Other formulas listed pertain to different geometric shapes or incorrectly apply trapezoidal principles.
