If `sqrt(2)=1.414 and sqrt(7)=2.646`, find the value of `(sqrt(2)+1)^2+(sqrt(7)+1)^2`.
The following stpes are involved in solving the above problem. Arrrange them in sequenatial order.
(A) `19.120`
(B) `11+2xx4.060=11+8-120`
(C) `11+2(sqrt(2)+sqrt(7))=11+2(1.414+2.646)`
(D) `(sqrt(2)+sqrt(1))^2+(sqrt(7)+1)^2=2+1+2sqrt(2)+7+1+2sqrt(7)`.

A

ABCD

B

DACB

C
