Question

the side of a triangle are in the ratio 1 upon 3 ratio 1 upon 4 ratio 1 upon 5 and its perimeter is 94 CM the length of the smallest side is tell me fast

Answer 1

it's 24cm.
$\frac{1}{3}x + \frac{1}{4}x + \frac{1}{5}x = 94 \\ \frac{20x + 15x + 12x}{60} = 94 \\ \frac{47x}{60} = 94 \\ 47x = 94 \times 60 \\ x = \frac{94 \times 60}{47} \\ x = 2 \times 60 \\ x = 120 \\ therefore \: smalest \: side \: = \frac{1}{5} x \\ = \frac{1}{5} \times 120 \\ = 24cm$

Answer 2

sol
$\frac{1}{3} . \frac{1}{4} . \frac{1}{5}$
point means ratio
taking LCM of 3,4,5= 60
multiply 60 by 1/3,1/4,1/5
the 20:15:12
now
total ratio 20+15+12=47
a=20*94/47=40cm
b=15*94/47=30cm
c=12*94/47=24cm
