Answer 2

Before, finding the answer. Let's find out how we can find the answer.

• In this question, we are asked to find the Perimeter of the Rectangle.

_____________________

Given :

• Length = 2 3/4 cm
• Breadth = 1 1/2 cm

To find :

• the perimeter of the rectangle

Solution :

⇒ Converting the mixed fraction to improper fraction.

Length = 2 3/4

            = (4 x 2 + 3)/4

            = (8 + 3)/4

            = 11/4 cm

Breadth = 1 1/2

             = (2 x 1 + 1)/2

             = (2 + 1)/2

             = 3/2 cm

⇒ Let's find the Perimeter of the Rectangle.

Perimeter of Rectangle = 2 (l + b)

                                       = 2 (11/4 + 3/2)

                                       = 2 (11 x 4/3 x 2)

                                       = 2 (44/6)

                                       = 2 x (44/6)

                                       = 2 x 44/6

                                       = 88/6

Therefore, the Perimeter of the Rectangle is 88/6 cm.
