The problem states that Length is 4 meters longer than the width.  This means you have the equation: L = W + 4.  Since the Perimeter is 60 meters, we just need to put this information into the formula for the perimeter of a rectangle.

P = L + L + W + W = 2L + 2W

60 = 2(W + 4) + 2W       Use the distributive property
60 = 2W + 8 + 2W         Collect like terms
60 = 4W + 8              Subtract 8 from both sides
52 = 4W                  Solve for W by dividing both sides by 4
13 = W; thus, W = 13 m

Now that we have the width, we have to find the length.  The Length is 4 meters longer than the width.  So, L = 13 + 4 = 17 m</PRE>
