👉 In geometry, a trapezoid is a quadrilateral with exactly one pair of parallel sides. It has four right angles and two pairs of opposite sides that are equal in length. Its area can be calculated using Heron's formula: Area = √(s(s - a)(s - b)(s - c)) Where: - s is the semiperimeter (half the perimeter) of the trapezoid, - a and b are the lengths of the parallel sides,
