What is the area formula for a trapezoid?

  1. BH

  2. 1/2 BH

  3. 1/2(B + H)

  4. 1/2(B + A)

The correct answer is: BH

The correct formula for the area of a trapezoid is based on the average of the lengths of the two parallel sides, which are often referred to as the bases, multiplied by the height of the trapezoid. The formula can be expressed as: Area = 1/2 × (Base1 + Base2) × Height This means that to find the area, you take the sum of the lengths of the two bases (parallel sides), divide that sum by 2 to find their average, and then multiply by the height (the perpendicular distance between the bases). In this case, the answer correctly highlights the relationship between the bases and height. The other options do not reflect the proper relationship for calculating the area of a trapezoid. For instance, simply multiplying by the height or using just one base would not represent the actual area, which requires accounting for both bases.
