If sqrt(2)=1.414 and sqrt(7)=2.646, then...

If `sqrt(2)=1.414 and sqrt(7)=2.646`, then find the value of `sqrt(32)+sqrt(252.)`

A

`20.839`

B

`21.532`

C

`19.482`

D

`22.231`

Text Solution

Verified by Experts

The correct Answer is:
B
`sqrt(32)+sqrt(252)`
`=4sqrt(2)+6sqrt(7)`
`=4xx1.414+6xx2.646`
`= 5.656 + 15.876`
`=21.532`
Hence , the correct option is (b).
