Question

3. The perimeter of a triangle is 14.4cm and the ratio
of lenghts of its side is 2:3;4
construct the triangle.​

Answer 1

Step-by-step explanation:

perimeter of a triangle is sums of all its sides

given ratio is 2:3:4

the ratio is cancelled by a number

let that number is x

2x+3x+4x=14.4 cm

x(2+3+4)=14.4

x=14.4/9

x=1.6

2x=3.2

3x=4.8

4x=6.4
