you want to know the area of a triangle without the height? it would be possible with the width and the length of one of the other two sides and the angle between the two sides of which you know the measurements if i remember my gcse maths... http://www.horacemann.org/academics/math/pcbch/trig/sohcahtoa.html or just search google for sohcahtoa trigonometry
