Calculate the area, perimeter of Trapezuim (Trapezium Calculator)  


 



Perimeter of Trapezium (trapezoid calc: find p) = a + b + c + d
where,
a, b, c, d = sides
Examples: how to work out the area of a trapezium?
Case 1: Find the area of a trapezium using the sides length as 4,5 and the height 2.
Step 1: Find the area.
Area = ½ * (a+ b) * h = ½ * (4 + 5) * 2 = ½ * 9 * 2 = 9.
Case 2: Find the perimeter of a trapezium using the sides length as 4,5,6,7
Step 1: Find the perimeter.
Perimeter = a + b + c + d = 4+5+6+7 = 22.
To find the side following calculation will be used (trapezoid calc: find c):
c =P  a  b  d
For Height:
trapezoid calc: find h, a=n/a, b=n/a, a=n/a
h=2*(A/(a+b))
For base a
trapezoid calc: find a, b=n/a, h=n/a, a=n/a
For base b
find b, a=n/a, h=n/a, a=n/a
Where: n/a is marked as NULL
