ab=100, ac= 300 => c=3b. : bc=200, ab=100 => c=2a => a=1.5b. Thus a+b+c = (1.5 +1 + 3) b = 5.5b : bc = 3 x b sq. =200 => b sq. = 200/3 = (2 x 100 ) /3 . Thus b = sq rt 2 / sq rt 3 x10 & a+b+c = sqrt2 /sq rt3 x10 x5.5 . No pen or paper required.
use another way more easier when we know a^2 , b^2 , c^2
+_110/V6.
(a+b+c)^2>>>>>
Very good !!! ( Brazil )
See the other comment (solution)
Not vy good: a+b+c
Oh, come on. There's nothing tricky about this at all.a = 100/bc = 200/b(200/b)*(100/b) = 300200*100/300 = b^2b = 8.165a = 100/b = 100/8.165 = 12.2474c = 24.495a+b+c = 44.907Now, what was tricky about that???
Square root of (eqn 1x2x3) abc=√(100×200×300)=√6×1000 ••••eqn4a=√6×5 eqn4/eqn2b=√6×10/3 eqn4/eqn3c=√6×10 eqn4/eqn1a+b+c=√6(5+10/3+10)=√6×55/3

😂😂😂😂😂

a = 100/b
c = 200/b
(200/b)*(100/b) = 300
200*100/300 = b^2
b = 8.165
a = 100/b = 100/8.165 = 12.2474
c = 24.495
a+b+c = 44.907
