The trapezoid area formula finds the area of a four-sided shape with one pair of parallel sides. Use A = ½(a + b)h, where a and b are the parallel sides and h is the height.
Solve it with the AI Math SolverA trapezoid has two parallel sides of different lengths, called bases. Because the parallel sides differ, the area formula averages them: A = ½ × (base₁ + base₂) × height.
Add the two bases, multiply by the perpendicular height between them, and take half. The height must be measured straight between the parallel sides, not along a slanted edge.
A trapezoid is a four-sided shape with exactly one pair of parallel sides. Those parallel sides are called the bases; the perpendicular gap between them is the height.
Add the two bases, multiply by the height, and halve the result: A = ½(a + b)h. The formula averages the two base lengths, since they differ in length.
