Answer 2

Question:-

A rectangular sheet of paper is 12 cm long and 10 cm wide. Find its perimeter.

Solution:-

Given: The sheet of paper is in rectangular form.

Length of sheet = 12 cm = 25/2 cm

and Breadth of sheet = 10 cm = 32/3

Now, Perimeter of rectangle = 2 (length + breadth)

= 2(25/2 + 32/2)

= 2[(25 * 3 + 32 * 3)/6]

= 2[(75 + 96)/6]

= 2(139/6)

= 139/3

= 46

Thus, the perimeter of the rectangular sheet is 46 cm.
