Homework Help: Precalculus

Posted by Cole on Friday, October 5, 2012 at 9:49pm.

There are 4 rectangular corrals of identical dimensions along the back wall of an existing barn using 200 ft of fencing.

The diagram has 4 rectangular corrals attached together but fencing is not needed on the back wall of the barn. The barn is above the 4 rectangular corrals.

I have x (front to back) as the length and y as the width. I am trying to figure out the function and dimensions (lxw) that will produce 4 corrals with a combined area of 1,680 ft^2 (give both solutions).

I came up with 200=5x+8y. I am not sure if it is right to start out.
