Question

Suppose you estimated square root of 12 by averaging a square like rectngle.What would be a reasonable estimation?​

Answer 1

3.5.

Explanation:

3^2 = 9

and 4^2 = 16 so the square root is between 3 and 4.

Take a rectangle 3.4 by 3.6:

the area = 3.4 * 3.6 = 12.24 so an estimate of the square root could be 3.5.

3.5 * 3.5 = 12.25.
