@Thoughts can you pleasse help me?

reemii · Answer

did you plot them?

anonymous · Answer

Detect the figure whether it is parallelogram , rectangle , square or any other one.

anonymous · Answer

ITS A TRAPEZOID

reemii · Answer

it seems this figure would be at least a trapezium.. then there's a formula

anonymous · Answer

trapezium or trapezoid?

reemii · Answer

google "area of trapezium". and you'll have your question almost answered.

reemii · Answer

or just http://en.wikipedia.org/wiki/Trapezoid#Area and seems like trapezium and trapezoid are the same?

anonymous · Answer

@reemii  how about the median?

reemii · Answer

|dw:1370438787066:dw|
is it not the average of the length of the two bases?

reemii · Answer

lenghts*

reemii · Answer

if you don't know about that (consquence of thales thm i guess), you could still find it by first finding the coordinates of x and y :|dw:1370438932224:dw|
and then computing the norm of (x - y).

but the first method is just simpler.
