Question 342391
The perimeter of a rectangle is 24 centimeters.  The length of the rectangle is four more than the width.  What is the length of the rectangle?


Let the length of the rectangle be L


Then its width = L - 4, since the length of the rectangle is four more than the width


Perimeter of any rectangle = 2L + 2W. Since the length and width of this rectangle = L and L - 4, respectively, and since its perimeter is 24 centimeters, then we can say that:


2L + 2(L - 4) = 24


2L + 2L - 8 = 24


4L  =  24 + 8


4L  =  32


L, or length = {{{32/4}}} or {{{highlight_green(8)}}} centimeters.
