The sides of a triangle are in the ratio 6:8:10. The perimeter is 120 cm. Find the length of the shortest side.

6 + 8 + 10 = 24 ... 24 r = 120 ... r = 5 ... 6 r = 30
let the sides be 6x, 8x, and 10x
then 6x+8x+10x = 120
x = 5
The shortest side is 6x = 6(5) = 30
(in effect that is what R_scott did)
btw, did you notice that the triangle is right-angled ?

6 x + 8 x + 10 x = 120
24 x = 120
x = 120 / 24 = 5
Shortest side = 6 x = 6 ∙ 5 = 30 cm
24 x = 120
x = 120 / 24 = 5
Shortest side = 6 x = 6 ∙ 5 = 30 cm
