Question

The sides of a
training are in the ratio 1:2:3. if perimeter is 30 cm . find its side ___​

Answer 1

Answer:

According to the question :-

1x+2x+3x = 30

6x = 30

x = 30/6 which is equal to 5

So answer is 5

By the way if we need to find its sides individually they are 5,10,15

So in this question answer is 5

Answer 2

Answer:

Perimeter= 30cm

(sum of all sides)= 30

1x+2x+3x= 30

6x= 30

x= 30/6

x= 5

1st side= 1x= 1×5= 5cm

2nd side= 2×5=10cm

3rd side= 3×5=15cm
