Let the lenght be L. Let the Wdith be W

You are told the area = 20 and that the width is length-8
So

So L is either 10 or -2. Since L cannot be negative, then L=10
Which makes W = 10-8 = 2

Answer by JBarnum(2146) (Show Source): You can put this solution on YOUR website!
w=width
l=length
w=l-8
A=lw
A=20

you should see that +2 and -10 add to get -8 and multiply to get -20

the length cant be negative
