Question

draw a triangle of perimeter 10cm and side are in the ratio 3:4:5​

Answer 1

Answer:

Sides are of length 2.5 cm, 3.33 cm and 4.17 cm.

Drawn as attached.

Step-by-step explanation:

Sides are in the ratio 3:4:5

Let's assume that the proportionality constant is x

According to the problem:

3x + 4x + 5x = 10

=> 12x = 10

∴ x = 10/12 = 5/6

Therefore, sides are of length 5/2 cm, 10/3 cm and 25/6 cm

= 2.5 cm, 3.33 cm and 4.17 cm.
