The lenth of a rectangle is 6 inches longer than its width. The perimeter of a rectangle is 28 inches. If x represents the width of the rectangle in inches which equation can be used to find its value
The perimeter is 2l+2w. If L is the width plus 6, 2l could be expressed as 2(w+6). With L replaced you would have 2(w+6)+2w=28 which you then could distribute, add like terms, and solve for w.
