Answer 1

The correct option is A $27.20$

We will use long division method

In this, first group the numbers into two starting from unit place, these groups are called periods.

use the largest number whose square is equal or less than the first period number

Subtract the product of divisor and quotient from the first period and bring down the second period to the right of remainder. This will become new divident.

In this way we can find out the square root .

Hence, Option A is correct.
