Question

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

Answer 1

sum of ratio terms = 2+3+4 = 9
1st side = 14.4×2/9 =3.2
2nd side = 14.4×1/3 = 4.8
3rd side = 14.4×4/9 = 6.4

Answer 2

Answer:

Step-by-step explanation:

Let the sides be a, b and c.

Now :

a : b : c = 2 : 3 : 4

a + b + c = 2 + 3 + 4 = 9 (sum of the ratios)

a + b + c = 14.4 cm

a = 2/9 × 14.4 = 3.2 cm

b = 3/9 × 14.4 = 4.8 cm

c = 4/9 × 14.4 = 6.4 cm

We will therefore construct a triangle of sides :

3.2cm, 4.8cm and 6.4 cm
