The garden is 9m long and is no wider than 10m. What is its width if you can walk the same 55cm or 70cm lengths?

Correct answer:

x =  7.5 m

Step-by-step explanation:

55=511 75=352 LCM(55,75)=35211=825  k=LCM(55,75)=825 x1=900/k=900/825=11121.0909 x2=(900+1000)/k=(900+1000)/825=33762.303 x=2 k/1009=2 825/1009=7.5 m
