Question

The perimeter of a triangle is 14.4 cm and the ratio of lengths of its sides 2:3:4. Construct the triangle

Answer 1

Answer:

The length of sides are

Step-by-step explanation:

It is given that the ratio of lengths of its sides 2:3:4.

Let the length of sides be 2x, 3x, 4x respectively.

Perimeter is the sum of all sides.

$2x+3x+4x=14.4$

$9x=14.4$

Divide both sides by 9.

$x=1.6$

The value of x is 1.6, therefore the length of sides are 3.2 cm, 4.8 cm, 6.4 cm.

Answer 2

Answer:

Step-by-step explanation:

Let lengths of the triangle be 2x,3x,4x cm respectively.

So,2x+3x+4x=14.4

X=14.4/9=1.6

Hence, lengths are 3.2cm,4.8cm and 6.4cm.Hope you understood.
