Provide an appropriate response.Explain how you could find an approximation to 
to the nearest tenth without using a calculator.
What will be an ideal response?
Possible answer. Use trial and error. Look for a number whose square is close to 90. Start by squaring whole numbers to determine that 
lies between 9 and 10. Then try numbers between 9 and 10 with one decimal to see which one has a square closest to 90. To the nearest tenth,
