Question 262172
Let x=width and 6x=length. 
The area formula for a rectangle is length times width. 
So x times 6x has to equal 96 ft^2. 
x times 6x multipy to become 6x^2.
So then the equation would be 6x^2=96 ft^2. 
You'd then divide both sides by 6 so it would look like: x^2=16ft^2. 
Find the quare root of both sides to balance operations and end up with x=4ft.
So the width is 4 ft.
And you'd plug in the 4 on the 6x to get 24.
Check: 4 times 24 DOES equal 96.
