We can find the length of the sides now by dividing 56 by 4, which gives us 19. Subtracting 5 from 19 gives us our answer of 14 feet.
Answer:

Step-by-step explanation:
-This is an LCM problem.
-To simplify, we introduce a least common multiplier which is equivalent the product of the denominators:

#We introduce the LCM and adjust the fractions based on it :

Hence, the simplified form of the fraction is: 
888 + 444 + 333 + 666 = 2331 / 7 = 3
3 * 222 = 666
There are 666 of the plants

No, Lily is not correct. This is because 16+3 does not equal 18. So to find N, you take 18 and subtract 16.
18-16=n
18-16=2
so n=2
16+2=18.
