Jaydin's Square Root Scribe post

5. Estimate each value, to one decimal place. Check your answer with a calculator.
a)14 b)86 c)136




7. Identify a whole number with a square root between 11 and 12.
125 if you square root 11 its 121 and if your square root 12 its 144 so 125 is a whole number between it. It could be any number between 121 to 144 also.

10. Kai uses an entire can of paint on a square backdrop for the school play. The label on the can states that can states that one can covers 27cm² of the wall surface. Estimate the backdrop's side length, to one decimal place.
