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 (b1 + b2) × h
where b1 is base1, b2 is base2 and h is height.
