Perimeter of a Trapezoid & Calculator

The perimeter of a trapezoid can be calculated using one of the following formula: if you know the length of each side.

Formula Knowing the Bases and one Side

If you know the length of one of the sides, you can calculate its perimeter using the following formula:

Trapezoid Perimeter

$$"perimeter" = a + b + c + d$$

$$a = "length of the "a" side"$$
$$b = "length of the "b" side"$$
$$c = "length of the "c" side"$$
$$d = "length of the "d" side"$$

Trapezoid Definition

It is a geometric figure with 4 sides, it has two parallel lines. All trapezoids have different angles.

A trapezoid can have vitually infinite posibles shapes, Despite this all have 4 sides and all this angles are different.

Perimeter Definition

A perimeter is defined by the outer path of a shape. The shape is always in 2 dimensions. The perimeter is the total length of the exterior path. Another way of looking at this is to think of it as the boundary length of a shape.

In the case of a circle, the perimeter is called a circumference.

Perimeter has a Greek origin, "peri" means "around", and "meter" means "measure". So perimeter means "measure around".
