equation of a straight line problem
how can you solve for the points of a rectangle given only its four equations? also,how can i get its area?...help me pls....i already tried solving its intersection but it doesnt work out well...:confused:

What you need to do is state the question exactly as it is written from where you got it from.

It sounds like you have four equations of lines which somehow intersect to form a rectangle (or some quadrilateral if you are confusing terms). What you would do to find its area is to take the double integral over the edges of the quadrilateral, taking care to ensure you have the correct boundaries and proper integration order. Without more context though, your qeustion cannot be answered.
