Trapezoid Area Calculator
The trapezoid area calculator can help you calculate the area of a trapezoid without having to remember any confusing formulas for so many different shapes. A trapezoid is defined as having 4 sides and at least one pair of parallel sides. If both sides are parallel this is known as a parallelogram and will be included in most mathematical cases as a trapezoid. You can see the specific formula for parallelograms on that specific page.
The broader formula for calculating the area of a trapezoid is average of the two parallel sides times the height. ((a+b)/2)H To calculate the height simply measure the shortest distance between the two parallel lines. This would be done by intersecting the two lines at a right angle.
To use our trapezoid area calculator simply enter the measurements for the sides and the height in the form fields and our calculator will do the rest. While it can be very difficult to keep track of the different area formulas for different shapes we recommend trying to learn the formulas if you are using this as an educational resource. Most exams would not allow the use of area calculators to aid with your calculations.
