construct a triangle ABC whose perimeter is 14cm and sides are in the ratio of 2:3:4 .
perimeter ot a tri. = sum of all sides
let the 3 sides of the tri. be 2a 3a nd 4a
a=1.6 (rounding the decimal nearest to ones)
therefore the 3 sides are 2*1.6, 3*1.6 nd 4*1.6 = 3.2, 4.8 nd 6.4
now u hav the measurement of the sides so u can construct the triangles accordind to the above found lengths
i hope it answers it :)
