If the width is w and the length is l, then 2w=l. In addition, l*w=88200 (using the area formula). Plugging 2w in for l, we get 2w*w=88200=2w^2. Dividing both sides by 2, we get w^2=44100 and w=sqrt(44100)=210.
-1/2 and -2 would be the answer
This would be because when you plug these number instead of x the answer is equal to or less than 13
sorry for using printed paper, I tried my best to avoid the lines
quadratic equations can be soled by 3 methods
factorization
completing square
quadratic formula
but factorization is the simplest
