Trapezium Formulas

1. Area of Trapezium Formula

$\mathrm{Area}=\frac{(a+b)}{2}\times h$

Area is the average of the two parallel sides (a, b) multiplied by height (h).

2. Perimeter of Trapezium Formula

$\mathrm{Perimeter}=a+b+c+d$

Perimeter is the sum of all four sides (a, b, c, d).

3. Height of Trapezium Formula (from Area)

$h=\frac{\mathrm{2\; \times \; Area}}{\mathrm{a\; +\; b}}$

Height is twice the area divided by the sum of the parallel sides (a + b).
