Sam recently has a Square garden. He wants to redesign his garden and make it into a rectangle with a length that is 3 feet shorter than twice it's width. He decides that the perimeter should be 60 feet. What are the dimensions,in feet, of his new garden.

1 answer

2L + 2W = P
2L + 2W = 60

L = 2W -3

2(2W-3) + 2W = 60
4W -6 + 2W = 60
6W = 66
w = 11
Can you find L?
