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

√c^{2} - ((b-a)^{2}+c^{2}-d^{2}
2·(b-a)
)^{2} =
·
√24.75^{2} - ((120.65625-95.90625)^{2}+24.75^{2}-37.125^{2}
2·(120.65625-95.90625)
)^{2} =
