What is the perimeter of a rectangular garden?

The perimeter of a rectangular garden is 1200 feet? The length of the garden is 300 feet more than twice the width. If l represents the length of the garden and w represents the width of the garden, which pair of equations should be used to determine the values of l and w?

L = 300 + 2W

P = 2L + 2W = 600 + 4W + 2W = 1200

6W = 1200 - 600

W = 600/6 = 100
L = 500

So, 500 + 500 + 100 + 100 = 1200

hope this it.
