Question

the perimeter of a triangle ABC is 13.5 cm and ratio of length of its side is 2 :3 :4 find the length of the three sides of the triangle

Answer 1

Let the sides be 2x,3x and 4x.
Perimeter=Sum of all sides.
13.5=2x+3x+4x
13.5=9x
x=1.5
1st side=2x=3 cm.
2nd side 3x=4.5cm
3rd side=4x=6 cm.
Hence,sides are 3cm,4.5cm and 6cm.Hope this helps!!Please mark as brainliest!!

Answer 2

Answer:

Step-by-step explanation:

Let the side be 2x, 3x ,4x

Ab=2x ,bc=3x, ac=4x

Perimeter = ab+bc+ac

13.5 = 2x+3x+4x

13.5 = 9x

13.5/9 = x

1.5 =x

Therefore

ab= 2x = 2×1.5= 3

bc =3x=3×1.5=4.5

ac =4x=4×1.5=6
