Question

The sides of a triangle are in the ratio of 2 : 3:4.
If the perimeter is 72 cm, find its sides.​

Answer 1

Answer:

16cm, 24cm, 32cm.

Step-by-step explanation:

Let the three sides be- 2a, 3a, 4a respectively.

Perimeter = 2a + 3a + 4a

We know that perimeter is 72 cm,

72 = 2a + 3a + 4a

72 = 9a

a = 72/9

a = 8 cm

Now replace the values.

side 2a = 2x8 = 16 cm

side 3a = 3x8 = 24 cm

side 4a = 4x8 = 32 cm

Answer 2

Answer:

16CM, 24CM, 32CM

Step-by-step explanation:

LET THE THREE SIDES BE-2A, 3A, RESPECTIVELY

PERIMETER-2A,+3A+4A

WE KNOW THAT PERIMETER IS 72CM

72=2A+3A+4A 72=9A

A=72/9 A=8CM

NOW REPLACE THE VALUES

SIDE 2A=2X8=16CM

SIDE 3A=3X8=24CM

SIDE4A=4X8=32CM
