What approximate value should come in place of the question mark (?) in the following questions ? (Note : You are not expected to calculate the exact value.)
$$14.5^{2}=?$$
Instead of finding the square of a decimal number, we could try writing it in the form of fractions.
Here, 14.5 can be written as $$\frac{29}{2}$$
$$29^{2}$$ = 841 and $$2^{2}$$ = 4.
$$\frac{841}{4}$$ = 210.25 ≈ 210.
Hence Option E is the correct answer.
