**Quidditch**, Saturday, January 5, 2008 at 11:17amArea of a triangle:

Area=(base * height)/2

Area of a trapezoid:

Area=height * (b1 + b2)/2

where:

b1=length of top side

b2=length of bottom side

**drwls**, Saturday, January 5, 2008 at 12:14pmQuiddithch is correct. The trapezoid's height is the distance between the two parallel sides, b1 and b2. For a triangle, you can choose any side for the base, but must measure the height from that chosen base when using the formula.
