Question

The sides of a triangle are in a ratio of 2:4:5.If the shortest side is 6 cm, the find the perimeter of the triangle.​

Answer 1

Answer:

perimeter is 33

Step-by-step explanation:

first let all sides as

2x ,4x,5x

now compare them :

2x < 4x < 5x now we got the shorter side 2x so

according to question

2x = 6 cm

x = 6/2 cm

x= 3 cm

now we have the value of x

so , put it in 2x, 4x, 5x

2× 3 = 6 cm

5×3= 15 cm

4×3= 12 cm

now we find its perimeter

2x+ 4x+5x

= (6 +12 +15 ) cm

= 33 cm

Answer 2

Answer:

ratio 2:4:5

value of 2 is 6

if value of 1  is 6/2=3

then value of 4 is 4 x 3 = 12

so value of 5 is 5 x 3 = 15
