Where does the formula of a trapezoid come from? 12(AB+CD)h , which is usually represented in words as “half-sum of the bases times the altitude”.

Why does the formula for a trapezoid work? The area of this parallelogram is its height (half-height of the trapezoid) times its base (sum of the bases of the trapezoid), so its area is half-height × (base1 + base2). Because the parallelogram is made from exactly the same “stuff” as the trapezoid, that’s the area of the trapezoid, too.
Who discovered the area of a trapezoid? Two types of trapezia were introduced by Proclus (412 to 485 AD) in his commentary on the first book of Euclid’s Elements: one pair of parallel sides – a trapezium (τραπέζιον), divided into isosceles (equal legs) and scalene (unequal) trapeziums.
