Question

draw a triangle of perimeter 10cm and it's side are in the ratio 2:3:4​

Answer 1

let the sides be 2x, 3x, and 4x

according to the question

perimeter = sum of all sides

10 = 2x+3x+4x

10= 9x

x=10/9

hence the sides are 2x= 2×10/9= 20/92= 2.2cm 3x= 3×10/9 =30/9 = 3.3cm

and 4x= 4×10/9 = 40/9 = 4.4cm
