Step-by-step explanation:
The area of a trapezoid is given by half sum of the bases multiplied by the height
where a and b are the two parallel sides of the trapezoid and h is the height or amplitude of the trapezoid
But you are aware that, the median of a trapezoid is equal to half the sum of the bases, thus the first part of the formulae is covered by the median
Hence area, A, of a trapezoid is simplified to product of median and amplitude
