Question

A rectangular sheet of paper is 12½cm long and 10⅔cm wide . Find its perimeter.​

Answer 1

Length of the rectangle sheet = 12 1 / 2 cm

⇒Breadth of the rectangle sheet = 10 2 / 3 cm

To find :-

⇒Perimeter = ?

Sol ;-

⇒ Perimeter of rectangle = 2 ( l + b )

⇒ { 2 ( 25 / 2 + 32 /3 }

⇒ { 2 ( 75 / 6 + 64 / 6 }

⇒ 2 × 139 / 6

⇒ 139 / 3 = 3 1/46 cm

Therefore the answer is ;- 3 1 /46 cm

Answer 2

Given :-

• length - 12½ cm
• wide - 10⅔ cm

To find :-

• perimeter

Solution :-

Perimeter :- 2 ( L + B )

» 2 ( 12½ + 10⅔ ) cm

» 2 ( 25 / 2 + 32 / 3 ) cm

» 2 ( 75 + 64 / 6 ) cm

» 2 ( 139 / 6 ) cm

» 46.3 cm

Thus, 46.3 cm is the perimeter.
