Where did you get these problems? They look like homework problems for an algebra or a "preCalculus" course, but you appear to be saying that you are not taking such a course!

Its from my math book, not a homework just trying to get this sorted and understand in an easy way possible. Basically self learn from the internet. Its a sec 4 math class book. I thought this website could be with self learning. I am good at it once i get the answer then try to learn from it and understand it in every possible way

You are told that s lies between 5 and 15 so s^2 lies between 5^2= 25 and 15^2= 225.
Then 6s^2 lies between 6(25)= 150 and 6(225)= 1350.
