A trapezoid (or trapezium in British English) is a quadrilateral with at least one pair of parallel sides (called bases). Its area formula is A = (1/2) × (sum of parallel sides) × height. If the parallel sides are a = 8 cm and b = 12 cm, and the height is 5 cm, then A = (1/2) × (8 + 12) × 5 = (1/2) × 20 × 5 = 50 cm². This concept applies to irregular land plots, architectural designs with sloped walls, and advanced geometry. Commanding trapezoid area calculations helps you analyze composite figures and real-world shapes more precisely.
