You collect the lengths of all 4 sides, and then add them up. Their sum is the perimeter.
To find the perimeter of a trapezium, add the lengths of all four sides together using the formula P = A + B + C + D. This method will provide the total distance around the trapezium. For instance, if the sides are 5 cm, 7 cm, 4 cm, and 6 cm, the perimeter is 22 cm.
