The area of a trapezium with parallel sides $a$ and $b$ and perpendicular distance $h$ between them is —

a $\dfrac{1}{2}(a + b)h$
b $(a$

ব্যাখ্যা

A trapezium's area is the average of the two parallel sides multiplied by the perpendicular height, i.e. $\tfrac{1}{2}(a+b)h$ . This averages the unequal parallel widths over the height.
