Designate the width in feet by w. By the statement of the problem, the length is then w+2. The area of any rectangle is the product of the length and the width, or w(w+2) = 8. Multiplying out and collecting all terms on one side yields w2 + 2w - 8 = 0. The polynomial can be factored into (w + 4)(w - 2) = 0, which is true when w = 2 or -4. The length of a physical rectangle can not be negative; therefore, the width is 2 feet and the length 4 feet.

How does length relate to area?
The area of a square or rectangle is the product of its two dimensions, so its length is the quotient when its area is divided by its width.

It is: 12 units in length
Does it matter which dimensions you select for the length and width when you find the area of a rectangle?
not really but the length is always the longer side :)

How much square ins is a rectangle?
Without the dimensions, we won't be able to tell. The area of a rectangle is the length times the width. If those dimensions are in inches, the area will be in square inches.

How to get the deminsions of a rectangle?
The dimensions of a rectangle are the length and the width. With these two measurements , the area of the rectangle can be calculated : Area = length x width. The perimeter can also be found : Perimeter = (2 x length) + (2 x width).
