Question

a rectangular sheet of paper is 11.1/2cm long 12.1/3cm wide.
find its perimeter ​

Answer 1

Answer:

575/30

Step-by-step explanation:

Perimeter of Rectangle = 2 ( Length + Breadth )

So here Length is 11.1/2 cm and Breadth is 12.1/3 cm

If we remove decimals from numerator then the no. after decimals is added to denominator in form of zeroes

For eg: 2.5/10 = 25/100

           3.456/89 = 3456/ 89000

So here if we remove the decimals:

111/20 and 121/30

Now LCM of 20 and 30 is 60

So after adding these 2 fractions we will get 575/60

Now the bracket is solved

We only have to multiply 2 by this fraction so:

2 x 575/60 = 575/30

Hope it helps :)
