Question 472651: How would i set up a system of equations for "The length of Sally's garden is 4 meters greater than 3 times the width. The perimeter of her garden is 72 meters." And how would i find the dimensions.
I do know that to find perimeter you use . I also defined my variables as length = x and width = y. So far if i am doing it correctly I have to represent the length if 4 meters greater than 3 times the width. Answer by richard1234(5390) (Show Source):
You can put this solution on YOUR website! Good start. However you haven't used the fact that the perimeter is 72. Since the length is x and width is y, we can say that 2(x+y) = 72 --> x+y = 36. Now you have a system of two equations that should be easy to solve for.
