The area of the triangle in the attachment has to be found.

It is not stated in the question what kind of a triangle it is nor are there any angles given.

I believe that there is information that has been left out of the diagram to solve this question (This is a question in a maths workbook by Schofields and Sims mental arithmathics 4).


Thanks in advance for the help.

The diagram has all the information needed. How do you find the area of a triangle?
 
No idea, i would've done it the easiest way which is to find the area of a rectangle and take away the areas of the two smaller triangles around the original triangle.
 
Thanks for the link. For some reason I didn't think 0.5xbxh = area would work with an oblique triangle..really silly of me
