The sides of a triangle are in the ratio of 1/2:1/3:1/4.
if the perimeter is 52 cm.the length of the smallest side is:
(A)9cm (B)10cm (C)16cm (D)24cm (E)12cm

-
- 1/2x+1/3x+1/4x=52
x=48
sides are 24, 16,12
smallest is 12 ans - 14 years agoHelpfull: Yes(11) No(0)
- The sides of a triangle are in the ratio of 1/2:1/3:1/4.
so, sides are x/2, x/3 and x/4.
And perimeter= x/2 + x/3 + x/4 = 52==> x= 48.
Therefore sides are 48/2, 48/3 and 48/4. i.e, 24, 16 and 12.
so, length of the smallest side = 12cm - 14 years agoHelpfull: Yes(8) No(0)
- answer is e 12 cm
1/2 x+ 1/3x+ 1/4 x=52
so x=48
so length of smallest side=1/4 x 48=12 cm - 14 years agoHelpfull: Yes(5) No(1)
- 1/2:1/3:1/4=6:4:3
so 6x+4x+3x=52
=>13x=52
=>x=4
smallest side=3*4=12cm - 14 years agoHelpfull: Yes(3) No(1)
- 12cm
- 14 years agoHelpfull: Yes(1) No(0)
- sides ratio will become 6:4:3
sides 6x, 4x, 3x
perimeter= 13x=53
x=4
smallest side of triangle= 3x4=12cm - 9 years agoHelpfull: Yes(0) No(0)
