How did you decide what the whole number part of your estimate should be for the square?
What do you think you could do to get a side length of the square that would produce a more accurate area? Is it possible to find a side length that would be perfect for a square with an area of 45 square units? Explain your reasoning.

  1. 45 = 5 * 9
    so
    sqrt 45 = 3 sqrt 5 = the side of the square
    The square root of 5 is an irrational number.
    sqrt 5 = 2.2360679775 etc etc etc not repeating , no exact answer
