How do you calculate the surface area of a trapezoid?

The surface area of a trapezoid is calculated using the equation 1/2(a+b)*h, where "a" and "b" are the parallel sides of the trapezoid, and "h" is the vertical height. For example, if side "a" equals three, side "b" equals five and height "h" equals four, then the area equals 1/2(3+5)*4, or 16.

How do you calculate the square footage of a trapezoid?

In this case you need the top edge, bottom edge, left side, right side. The formula for a trapezoid is: Square footage Trapezoid= Height* (top edge + bottom edge)/2.

How do you calculate the angles of a trapezoid?

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.

What is the equation for a trapezoid?

How to Find the Height of a Trapezoid. Set up the equation for the area of a trapezoid. Write A=h(b1+b2)/2, where A represents the trapezoid’s area, b1 represents one of the base lengths, b2 represents the other base length and h represents the height. Rearrange the equation to get h alone. Multiply both sides of the equation by 2 to get.
