# How to calculate trapezoid area

A trapezoid is a four-sided geometric shape with two parallel sides called bases. These bases are of different lengths, which gives the trapezoid its unique shape. The other two sides, called legs, are not parallel. Calculating the area of a trapezoid can be useful in various applications, ranging from simple math problems to more complex engineering tasks. In this article, we will discuss how to calculate the area of a trapezoid using a straightforward method.

To calculate the area of a trapezoid, follow these steps:

**1. Identify the Measurements**

Firstly, you’ll need to know the measurements of your trapezoid. Specifically, you need the lengths of both bases (b1 and b2) and the height (h).

**2. Add the Lengths of the Bases**

Next, add the lengths of both bases together:

**sum_of_bases** = b1 + b2

**3. Calculate the Average of the Bases**

Divide the sum of bases by 2 to get their average:

**average_of_bases =** sum_of_bases / 2

**4. Multiply by Height**

To find the area, multiply the average of bases by the height:

**area =** average_of_bases * h

**5. Result**

Now you have calculated the area of your trapezoid.

As an example, let’s calculate the area for a trapezoid with base lengths 5 and 7 units and a height of 4 units:

**1) Identify measurements:**

**b1 =** 5 units

**b2 = 7** units

**h =** 4 units

**2) Add lengths:**

**sum_of_bases =** 5 + 7 = 12

**3) Calculate average:**

**average_of_bases =** 12 / 2= 6

**4) Multiply by height:**

**area =** 6 * 4 = 24

**5) Result:**

The area of the trapezoid is 24 square units.

Calculating the area of a trapezoid is a simple and practical skill with various applications. Remember to follow the steps outlined in this article, and you’ll be able to efficiently determine the area of any trapezoid.
