Well we can find the perimeter by using the formula P=2L + 2W 
P=2(30) + 2(18)      P=60+36     P=96
I believe we can divide the perimeter by 18 to find the total amount of lights needed. 
96÷18=5.333333 
So we know at least 5 lights are needed.
I'm not sure if I'm correct, but I hope this helped anyways :)
