Question

perimeter of traingle is 600 m.if the ratio is 12:13:15 then find the longest side

Answer 1

let side of triangle eq. x
so sides are 12x,13x,15x
so A.T.Q.
perimeter=sum of all sides
=600=12x+13x+15x
=600=40x
600/40=x
x=15
so sides are=12×15=180
=13×15=195
=15×15=225
so third side is longest
