Question

The perimeter of a triangle is 14.4 and the ratio of lengths of its side is 2:3:4

Answer 1

Step-by-step explanation:

Assumption: Let the sides be 2x, 3x and 4x units respectively.

According to the question,

2x + 3x + 4x = 14.4

Or, 9x = 14.4

Or, x = 14.4/9

Or, x = 1.6

Therefore, the sides are

2x = 2 × 1.6

= 3.2 units

3x = 3 × 1.6

= 4.8 units

4x = 4 × 1.6

= 6.4 units

Answer 2

Answer:

2x+3x+4x=14.4

9x=14.4

x=14.4/9

x=1.6

∴2*1.6=3.2

∴3*1.6=4.8

∴4*1.6=6.4
