The image above is a trapezium.

To compute the perimeter of a trapezium, four essential parameters is needed and they are the length of the side (a), length of the side (b), length of the side (c) and length of the side (d).

The formula for calculating the perimeter of a trapezium is;

P = a + b + c + d

Where;

P = Perimeter of the trapezium

a = length of the side

b = length of the side

c = length of the side

d = length of the side

Let’s solve an example;

Find the perimeter of a trapezium with length of side (a) 4 cm, length of side (b) 8 cm, length of side (c) 12, length of side (d) 17 cm.

This implies that;

a = length of side = 4 cm

b = length of side = 8 cm

c = length of side = 12 cm

d = length of side = 17 cm

P = a + b + c + d

P = 4 + 8 + 12 + 17

P = 41

Therefore, the **perimeter of the trapezium** is **41 cm.**
