Match the items of List-I with those of List-II (Here ∆ denotes the area of △ABC.)

List I

List II

A) ∑cot‌A

I) (a+b+c)2‌

4∆

B) ∑cot‌

II) (a2+b2+c2)‌

4∆

C) If tan‌A:tan‌B:tan‌C=1:2:3, then sin‌A:sin‌B:sin‌C=

III) 8:6:5

D)If cot‌

:cot‌

=3:7:9, then a:b:c=

IV) 12:5:13

V) √5:2√2:3

(VI) 4Δ

Then the correct match is
