Question

A rectangular sheet of paper is 5 2/3 cm long and
3 1/5 cm wide. Find its perimeter.​

Answer 1

Answer:

17 11/15 cm

Step-by-step explanation:

Length of rectangular sheet = 5⅔ cm = 17/3 cm

Breadth of rectangular sheet = 3⅕ cm = 16/5 cm

Perimeter = 2(l+b) = 2 (17/3 + 16/5) = 2(133/15) cm = 266/15 cm = 17 11/15 cm

Answer 2

Answer:

266/15 cm or 7 11/15 cm is the rectangle's perimeter.

Step-by-step explanation:

Length = 5 2/3 cm

=> [(3*5) + 2]/3

=> (15 + 2)/3 => 17/3 cm

Breadth = 3 1/5 cm

=> [(5*3) + 1]/5

=> (15 + 1)/5 => 16/5 cm

Perimeter of a rectangle = 2(l + b)

=> 2(17/3 + 16/5)

=> 2({85 + 48}/15)                (Making their denominators equal by equating them to 3 and 5's HCF which is 15)

=> 2(133/15) => 266/15 cm or 17 11/15 cm is the rectangle's perimeter.
