Trapezoid

A trapezoid is a quadrilateral whose two sides are parallel (bases) and the other two are not parallel (sides).
Trapezoid area formula Trapezoid area formula Through bases and height where a and b are bases, h is height

Solution:
S =
(a+b)·h
2
=
(11+11)·40
2
=
22·40
2
=
880
2
=
440

Answer: the area of a trapezoid with bases 11,11 and height 40 equal to 440
