To calculate the area of a trapezoid, identify the measurements of the two parallel sides and the distance between them. Put those numbers into the formula for calculating the area of a trapezium, and solve the equation.
Know MoreIn some cases, the length of the two sides might be given as part of the problem. In other circumstances, the lengths may need to be calculated from other information. The lengths of the other two, nonparallel sides are not necessary to calculate the area.
This measurement is also called the height of the trapezoid. In some cases, this measurement is given as part of the problem. At other times, it might need to be calculated from other information given about the figure.
The formula for calculating the area of the trapezoid is quite simple: 1/2 x (a+b) x height, where "a" and "b" are the lengths of the two parallel sides. To put this into words, add the lengths of the two parallel sides together, and divide it in half. Then, multiply that answer by the height of the trapezoid. The resulting answer is the area of the trapezoid.
The formula is Area = ½ times (Base times Height) or Area = (Base times Height) divided by 2. Finding the area of an isosceles or right triangle is easy as long as the length of the base and the height are known.

Full Answer >Calculate a truss angle by first measuring the truss's base, the horizontal piece parallel to the unit's ceiling. Look for the horizontal distance from the edge of the base to the point directly below the peak. For symmetrical trusses, this equals one half of the base's length.
Full Answer >The area of a trapezoid is found by multiplying the average length of the two parallel bases by the height, or 1/2 (b1 + b2) x h. The height is the length of a line connecting one base to the other at a 90-degree angle.
