Our calculation takes care of all the unit conversions for you and allows you to enter and compute variables in a wide variety of units. Area 1 2 31 21 5 a r e a 1 2 31 21 5. 332 base of a trapezoid p332 height of a trapezoid.
Z see figure above m in Wetted Perimeter.
The formula for the area of a trapezoid is A ½b 1 b 2h where b 1 and b 2 are the lengths of the bases and h is the height. The calculation essentially relies on the fact a trapezoids area can be equated to that of a rectangle. Area of B ½b h ½ 20m 14m 140m 2. The formula for the area of a trapezoid is A ½b 1 b 2h where b 1 and b 2 are the lengths of the bases and h is the height.
