Ok it seems simple but i cant get the answer
An architects computer package draws the cross section of a shed on its screen by drawing the area bounded by the x-axis and the y-axis and the lines
x=2.4, 2y=6.8-x & 2y=x+4.4
If each unit on each axis represents 1 metre, calculate the area
So i know the answer is 6m² i just got figure out how i got there ok
Thannnnnksss =]
Its quite straightforward, really. Plot the graphs to see what sort of the area you need to calculate. Determine the relevant points of intersection, and then calculate the area.

You can plot the lines using this: Function Grapher and Calculator (you can plot 2 lines, so could see their intersection point, but to be accurate you should do some algebra to figure out the value, too)
Example: Plot of (6.8-x)/2 vs (x+4.4)/2
And figure out the are using this method: Area of Irregular Polygons
