The formula for the area of a trapezoid is 1/2(base1 + base2)*altitude. Altitude is the height of the trapezoid. ChaCha on!
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.
Trapezoid Area = (base1+base2)/2 * height. Thanks for using ChaCha.
To find the area of a trapezoid, use this equation, a and b are the two straight sides.: Area = 0.5* h * (a + b)
