**Calculating the Area of a Trapezoid**

A trapezoid is a quadrilateral (has 4 sides) and has only one pair of sides parallel. Area of a Trapezoid means the number of square units it takes to completely fill a trapezoid.

**Formula: Average width × Altitude**

How to determine the area of a trapezoid:

- Add the lengths of the 2 parallel sides
- divide by 2 to get the average length of the parallel sides.
- Multiply this by the height (distance between the parallel sides

To find the area of a trapezoid, take the sum of its bases, multiply the sum by the height of the trapezoid, and then divide the result by 2. The formula for the area of a trapezoid is:

A = ½ (b_{1} + b_{2}) **× **h

where b_{1} is base_{1}, b_{2} is base_{2} and h is height.
