Which quantities define the area of a trapezoid in its standard formula?

Explanation:
Trapezoid area comes from the two bases and the distance between them. Since a trapezoid has two parallel sides, the area is the average of those base lengths (b1 and b2) times the height (h): A = ((b1 + b2)/2) × h. That’s why the quantities that define the area are the two bases and the height. The other options mix in elements not used in this formula—radius would relate to circles, a diagonal isn’t part of the area calculation, and using just one base wouldn’t capture a trapezoid’s two-width shape.
