Calculation:
As, \(\sqrt{360}\) = 18.97 and \(\sqrt{170}\) = 13.03
Here, we have
( \(\sqrt{360}\) + 12 ÷ 6 × 3 \(\sqrt{170}\) )÷ 2
(18.97 + 12 ÷ 6 ×3 - 13.03) ÷ 2
(18.97 + 2 × 3 - 13.03 ) ÷ 2
( 18.97 + 6 - 13.03 ) ÷ 2
( 24.97 - 13.03) ÷ 2
⇒ 11.94 ÷ 2 = 5.97 ≈ 6
Hence, the required approximate value is 6 .
