Question

2. A rectangular sheet of paper is 12 1/3 cm long and 10 2/3 cm wide. Find its
(i) perimeter (ii) area.

​

Answer 1

Step-by-step explanation:

1) Perimeter = 2×36/3+2×32/3= 24+64/3=136/3=45.33. 2) area = 36/3 × 32/3 = 128 is answer

Answer 2

Step-by-step explanation:

Length = 12 1/3 = 37/3

Breadth = 10 2/3 = 32/3

i) Perimeter of the rectangle :

$\rightarrow$ 2(l + b)

$\rightarrow$ 2(37/3 + 32/3)

$\rightarrow$ 2(69/3)

$\rightarrow$ 2(23)

$\rightarrow$ 46 cm

ii) Area is the rectangle :

$\rightarrow$ l × b

$\rightarrow$ 37/3 × 32/3

$\rightarrow$ 1184/9

$\rightarrow$ 131.5 cm²

Perimeter = 46 m ; Area = 131.5 cm²
