To estimate: The square root

Answer to Problem 51SR
Estimated value of
Explanation of Solution
Given information: A square root
Concept used: It is to find two perfect square numbers in between those, the number 140 lies and square root of its closest that perfect square number becomes the estimated value of square root of 140.
Calculation: As 140 lies between two perfect square numbers 121 and 144, so that 121 is square of 11 and 144 is square of 12, and also 140 is closest to 144, thus, value of
Conclusion: Thus, by above concept, it is cleared that as 140 is close to perfect square 144, its square root value 12 will also be the value of
