Formula For Area Of A Trapezoid Math
Area of a trapezoid.
Formula for area of a trapezoid math. The area a a of a trapezoid whose bases are a a and b b and whose height is h h is a a b h 2 a a b h 2 in other words the area of a trapezoid is the average of the two bases times its height or altitude. Below is a unit square with side lengths of 1 cm. In the formula the long and short bases are a and b and the altitude is h. As the size of the trapezoid changes the area is recalculated.
Another way to find the area of a trapezoid is to determine how many unit squares it takes to cover its surface. A r e a a b 2 h. The area a of a trapezoid using the length of the midsegment is. Try this drag the orange dots to move and resize the trapezoid.
Substituting the value for m into the original trapezoid area formula. The formula for the area of a trapezoid is the average of the bases multiplied by the altitude.
