If the length of the fence of a trapezium shaped field ABCD is 130m and side is perpendicular to each of the parallel side AD and BC.if BC=54m ,CD=19m and AD=42m, find the area of the field.

Answer 1

If I understand you to mean that AB┴AD and BC, then

BC-AD=12 and h=AB=√(19^2-12^2)=√217

so, the area is (42+54)/2 √217
