# Perimeter of trapezium calculator

**To calculate the perimeter of a trapezium (or trapezoid), you need to add up the lengths of all its four sides. Here’s how you can use a calculator to find the perimeter of a trapezium:**

- Measure the length of the top base of the trapezium.
- Write down the length of the top base.
- Measure the length of the bottom base of the trapezium.
- Write down the length of the bottom base.
- Measure the length of one of the slant sides of the trapezium.
- Write down the length of the slant side.
- Measure the length of the other slant side of the trapezium.
- Write down the length of the other slant side.
- Add up the lengths of all four sides.
- The result is the perimeter of the trapezium.

Alternatively, you can use the following formula to calculate the perimeter of a trapezium:

**Perimeter = Top Base + Bottom Base + Slant Side 1 + Slant Side 2**

Here’s an example to illustrate the process:

Suppose you have a trapezium with a top base length of 8 meters, a bottom base length of 12 meters, and slant sides of 6 meters each.

**To find the perimeter of this trapezium, you would follow these steps:**

- Measure the length of the top base: 8 meters.
- Write down the length of the top base: 8 meters.
- Measure the length of the bottom base: 12 meters.
- Write down the length of the bottom base: 12 meters.
- Measure the length of one of the slant sides: 6 meters.
- Write down the length of the slant side: 6 meters.
- Measure the length of the other slant side: 6 meters.
- Write down the length of the other slant side: 6 meters.
- Add up the lengths of all four sides: 8 + 12 + 6 + 6 = 32 meters.
- The perimeter of the trapezium is 32 meters.
