Question

the length of two rods are in the ratio 4:9 the longer length is 72 cm what is the shorter length ​

Answer 1

Hi,

Given:

Ratio of lengths of the rod=4:9

Longer length=72cm

To Find:

The shorter length

Solution:

Take the length of the length of longer rod to be 9x which is given as 72cm

Therefore 9x=72

                   x=72/9

                   x=8

Now take the length of shorter rod to be 4x

Substitute the value of x

We get,

4x=4×8=32cm

Therefore length of shorter rod is 32 cm

hope this helps you.

Answer 2

Answer:

the answer will 32 cm

Step-by-step explanation:

take the length of the longer rod to be 9x which is given as 72 cm

therefore 9x=72

x=72/9

x=8

now take the length of the shorter rod to be 4x

substitute the value of x

we get.

4x=4*8=32cm
