The length of a rectangle is 2 inches more than its width. The perimeter of the rectangle is 24 inches. The equation 2x + 2(x + 2) 24
where x is the width in inches, represents this situation,
so, the width of the rectangle is
inches and its
The value of x from the set (1, 3, 5, 7) that holds true for the equation is
length is inches.
