Perimeter of a Trapezium (Trapezoid)
P = a + b + c + d
Where: P = Perimeter, a = a, b = b, c = c, d = d
Use the same units for all lengths (e.g. all in cm); areas come out in cm², volumes in cm³.
Solved example
Given: a = 7, b = 5, c = 10, d = 4
Find: P (Perimeter)
- Formula: P = a + b + c + d
- Substitute the values: P = 10 + 4 + 5 + 7
- Result: P = 26
Answer: P = 26
