Introduction to Trapezoid Area Calculator

The area of trapezoid calculator is an online tool used to calculate the size of a trapezoid using the area formula. In other words, it is used to calculate the space covered by the sides of the trapezoid. It can be estimated by giving the length of the trapezoid sides and their height as an input. If you are confused about how to find the area of a trapezoid? It provides you detailed solutions and accurate results.

In geometry, we use different formulas to find the area of different shapes. It helps to discuss the geometrical properties of a body. That’s why here we introduce a tool online that can quickly find the area of the trapezoid.

Formula used by Trapezoidal Calculator

This calculator uses the area formula for trapezoids to calculate the space occupied by its sides. The formula is given as:

$$ A \;=\; \frac{1}{2}(a \;+\; b) \;×\; h $$


a and b are the sides of the trapezoid and h is the height.


How to calculate the area of the trapezoid whose length of the side a is 21 inches and the base b is 11 inches. And the height h is 5 inches.


To find the area of trapezoid, we use the following formula,

$$ A \;=\; \frac{1}{2}(a \;+\; b) \;×\;h $$


a=21 inch , b=11 inch and h=5 inch


$$ A \;=\; \frac{1}{2}(21 \;+\; 11) \;×\; 5 \;=\; \frac{1}{2}(32 \;×\; 5) $$ $$ A \;=\; 80inch^2 $$

How to use a Trapezoid Formula Calculator?

There are some simple steps to using this tool. These steps are:

  1. Search for from your desired browser, or you can access it on your android phone from the play store.
  2. There will be a list of different tools available on the website.
  3. Select the trapezoid calculator from the list.
  4. On the trapezoid tool page, you need to enter the values for the length of the sides of the trapezoid and its height in the respective boxes.
  5. Click on the “Calculate” button.

You will get the solution to the given problem with this trapezoid area calculator after a few seconds of pressing the calculate button.

Why use the Trapezoid Area Rule Calculator?

We often use the area formula to calculate the area for different shapes in geometry. But sometimes, you may forget the exact formula to calculate the size. For example, you may use the recipe for the area of a triangle instead of using the formula for the trapezoid. So that’s why you need to use a tool that can accurately apply the correct formula to the given problem. You can use the trapezoidal calculator to solve any problem.

Benefits of using the Area of Trapezoid Calculator

The trapezoid area formula is used to find the area of any trapezoid that helps to discuss the geometrical properties. We can see its area more easily with the area calculator. Some other beneficial uses of this tool are:

  1. It finds the area of the trapezoid accurately.
  2. You can find the solution by giving the values of the sides and height of the trapezoid. You don’t need to calculate every term of the formula manually.
  3. Trapezoid area calculator saves your time from manual solutions.
  4. You don’t need to pay any fee to use the area of a trapezoid calculator.
  5. You can solve more examples with its use so that you may be able to understand the formula.
