Answer:
The length of the garden is 3x+4
Explanation:
Since we can say that the garden has a rectangular geometry, then the perimeter is:
P=2w+2l
Being w and l, the with and the length respectively. We both know the perimeter and the width:
P=8x+8
w=x
If we replace in the perimeter equation above:
8x+8=2x+2l
By solving for the length l:
l=(8x+8-2x)/2
l=(6x+8)/2
l=3x+4
