Question 106449: A rectangular corral built with 190 meters of fencing that includes four separate grazing areas lies on a 962 meters squared rectangular plot of land. The fence that divides the grazing areas is parallel to two of the sides of the corral. If there is a 1 meter strip of land between each side of the corral and the property line, find the dimensions fo the corral. There may be more than one answer.

the perimeter (2W+2L) of the corral plus 3 interior fences (3W) is 190, so 5W+2L=190 ... let x=length, so (190-2x)/5=width

the area of the corral (LW) plus the 1 m border is 962 ... (x+2)((190-2x+10)/5)=962

(x+2)(200-2x)=5*962 ... 200x-2x^2+400-4x=4810 ... x^2-98x+2205=0

use quadratic formula to find x
