if this is a trapezoid like this:
******________6________
*****/*********************** \
****/8*************************\ 13
***/*****************************\
**/_________17_____________\
you can use the formula:
If the sides are a, b, c and d, and a and c are parallel (where a is the longer parallel side), then:
A= (a+c)/4(a-c) x sq rt of (a+b-c+d)(a-b-c+d)(a+b-c-d)
If the trapezoid above is divided into 4 triangles by its diagonals AC and BD, intersecting at O, then the area of ΔAOD is equal to that of ΔBOC, and the product of the areas of ΔAOD and ΔBOC is equal to that of ΔAOB and ΔCOD. The ratio of the areas of each pair of adjacent triangles is the same as that between the lengths of the parallel sides.
