(7/2) m is the width and 18m is the length. This is because area is lxw.let w= width and length=11+2wMultiply together, get 2w^2+11w-63=0factor to get (2w-7)(w+9).Find w and get w=7/2 and w=-9Negative rejected because a measurement can't be negative. Finally substitute that into the length equation (11+2w) to get 18m and width is 7/2 m

![2x+3y=-1;-2x-3y+1=1](https://tex.z-dn.net/?f=2x%2B3y%3D-1%3B-2x-3y%2B1%3D1)
Solve 2x+3y=−1 for x
![2x+3y=-1\\2x+3y+-3y=-1+-3y](https://tex.z-dn.net/?f=2x%2B3y%3D-1%5C%5C2x%2B3y%2B-3y%3D-1%2B-3y)
(Add -3y to both sides)
![2x=-3y-1\\\frac{2x}{2}=\frac{-3y-1}{2}](https://tex.z-dn.net/?f=2x%3D-3y-1%5C%5C%5Cfrac%7B2x%7D%7B2%7D%3D%5Cfrac%7B-3y-1%7D%7B2%7D)

Substitute
![-2x-3y+1=1\\-2(\frac{-3}{2}y+\frac{-1}{2})-3y+1=1\\2=1\\2+-2=1+-2\\0=-1\\](https://tex.z-dn.net/?f=-2x-3y%2B1%3D1%5C%5C-2%28%5Cfrac%7B-3%7D%7B2%7Dy%2B%5Cfrac%7B-1%7D%7B2%7D%29-3y%2B1%3D1%5C%5C2%3D1%5C%5C2%2B-2%3D1%2B-2%5C%5C0%3D-1%5C%5C)
