Are you struggling to calculate the area of a right trapezoid? Don’t worry! In this step-by-step guide, we will walk you through the formula and the required steps to find the area of a right trapezoid. Let’s dive in!

What is a Right Trapezoid?

Before we begin, let’s ensure we are on the same page about what a right trapezoid is. A right trapezoid is a quadrilateral with only one pair of opposite angles that are right angles. It has two parallel sides, where one side is longer than the other.

The Formula

To calculate the area of a right trapezoid, you can use the following formula:

Area = ((a + b) / 2) × h

  • a: Length of the longer parallel side (also known as the base)
  • b: Length of the shorter parallel side (also known as the top)
  • h: Height of the trapezoid (the perpendicular distance between the parallel sides)

Step 1: Measure the Length of the Longer Parallel Side (a)

Firstly, use a measuring tool, such as a ruler, to measure the length of the longer parallel side of the trapezoid. Let’s call this length ‘a’.

Step 2: Measure the Length of the Shorter Parallel Side (b)

Using the same measuring tool, measure the length of the shorter parallel side of the trapezoid. Let’s call this length ‘b’.

Step 3: Measure the Height of the Trapezoid (h)

Now, it’s time to determine the height of the trapezoid. Measure the perpendicular distance between the longer and shorter parallel sides. This distance is the height of the trapezoid and will be labeled as ‘h’.

Step 4: Apply the Formula

With all the required measurements, you are ready to calculate the area. Plug the values of ‘a’, ‘b’, and ‘h’ into the formula:

Area = ((a + b) / 2) × h

Using a calculator, perform the necessary mathematical operations and find the area of the right trapezoid.

Example Calculation

Let’s consider an example where ‘a’ is 8 cm, ‘b’ is 4 cm, and ‘h’ is 6 cm. By substituting these values into the formula, we get:

Area = ((8 + 4) / 2) × 6

Area = (12 / 2) × 6

Area = 6 × 6

Area = 36 cm²

Final Thoughts

Calculating the area of a right trapezoid is a simple process if you follow these steps and use the provided formula. Remember to accurately measure the lengths of the parallel sides and the height to get an accurate result. Now that you have learned this methodology, you can confidently solve any right trapezoid area calculation!
