Enter the lengths of all four sides of the trapezoid into the calculator to determine its perimeter; this calculator can also evaluate any of the side lengths given the perimeter is known.
Perimeter Of A Trapezoid Formula
The following formula is used to calculate the perimeter of a trapezoid:
P = a + b + c + d
Variables:
- P is the perimeter of the trapezoid
- a is the length of the first parallel side
- b is the length of the second parallel side
- c is the length of the first non-parallel side
- d is the length of the second non-parallel side
To calculate the perimeter of a trapezoid, add the lengths of all four sides together.
What is a Perimeter Of A Trapezoid?
The perimeter of a trapezoid is the sum of the lengths of all its four sides. A trapezoid is a four-sided polygon with one pair of parallel sides known as the bases and two non-parallel sides known as the legs. To calculate the perimeter of a trapezoid, you simply add the lengths of these four sides together. This is true regardless of whether the trapezoid is right-angled, isosceles, or scalene. The formula for the perimeter of a trapezoid is P = a + b + c + d, where a and b are the lengths of the bases, and c and d are the lengths of the legs.
How to Calculate the Perimeter Of A Trapezoid?
The following steps outline how to calculate the Perimeter of a Trapezoid.
- First, determine the length of the two parallel sides of the trapezoid (a and b).
- Next, determine the length of the two non-parallel sides of the trapezoid (c and d).
- Next, add the lengths of all four sides of the trapezoid together (a + b + c + d).
- Finally, calculate the Perimeter of the Trapezoid.
- After inserting the values and calculating the result, check your answer with the calculator above.
Example Problem:
Use the following values as an example problem to test your knowledge.
Length of parallel side a = 8
Length of parallel side b = 12
Length of non-parallel side c = 5
Length of non-parallel side d = 7
