Calculate the area and perimeter of a scalene trapezium (trapezoid). A scalene trapezium is a shape where two different length bases run parallel to each, and the connecting legs have different lengths.
This calculator can be used for different types of trapeziums (isosceles, right-angled, obtuse) when you know the length of all four sides.
Scalene trapezium = all sides having a different length, and the four angles are unequal.
0.5hy= √(s(s-c)(s-d)(s-y)) A = (a+b)/2*h P = a+b+c+d where h is the height of the trapezium y the length of the base = b – a s = 0.5(c+ d + y) a is the short base length b the long base length c the length of a leg d the length of the other leg A is the area P the perimeter of the trapezium
