Answer:
L = 42
W = 18
Step-by-step explanation:
I'm assuming that you want to know the width and the length of the garden. The procedure to do this is the following:
First, we know that the Length is 6 feet more than twice the width, this in other words, means:
L = 6 + 2W
So, let's call W as X
The perimeter of the garden is 120 and the expression to calculate is:
P = 2W + 2L
Replacing all the values in the above expression we have the following:
120 = 2x + 2(6 + 2x)
Solving for x we have:
120 = 2x + 12 + 4x
120 - 12 = 6x
108 = 6x
x = 108/6
x = 18
So the Width is 18, therefore the Length:
L = 6 + 2(18)
L = 6 + 36
L = 42
