Trapezoid Area Calculator tool is used to calculate area of a trapezoid, when the two base b1, b2 and height h is known.
The definition that most north American mathematicians use for trapezoid is a four-sided shape with exactly one pair of opposite sides parallel.
A trapezoid is a quadrilateral that has one pair of sides which are parallel. These two sides are called the bases of the trapezoid. The height of a trapezoid is a segment that connects the one base of the trapezoid and the other base of the trapezoid and is perpendicular to both of the bases.
b1=the one base of the trapezoid
b2=the other base of the trapezoid
h=the height of the trapezoidAltitude
An altitude of a trapezoid is a segment drawn from any point on one of the parallel sides (base) perpendicular to the opposite side (the other base). An infinite number of altitudes may be drawn in a trapezoid.Median
A median of a trapezoid is the segment that joins the midpoints of the nonparallel sides (legs).
