Formula: Trapezoid Area First side length Height
$$A ~=~ \frac{1}{2} \, (a ~+~ b) \, h$$
$$A ~=~ \frac{1}{2} \, (a ~+~ b) \, h$$
$$a ~=~ \frac{2A}{h} - b$$
$$b ~=~ \frac{2A}{h} - a$$
$$h ~=~ \frac{2A}{a + b}$$
Area
$$ A $$ Unit $$ \mathrm{m}^2 $$
Area of a trapezoid. A trapezoid is a quadrilateral with two parallel sides of length \(a\) and \(b\).
First side length
$$ a $$ Unit $$ \mathrm{m} $$
The length of one of the two parallel sides of the trapezoid.
Second side length
$$ b $$ Unit $$ \mathrm{m} $$
The length of one of the two parallel sides of the trapezoid.
Height
$$ h $$ Unit $$ \mathrm{m} $$
The height from the trapezoid, that is, the distance between the sides \( a \) and \( b \).
