Question

A rectangular sheet of paper is 16 1/2cm long and 12 2/3cm wide. Find its perimeter ​

Answer 1

Answer:

Given that

rectangular sheet paper (l) = 16 1/2cm

". ". " ". ". ". (b) = 12 2/3 cm

perimeter of rectangle = 2(l+b)

=> perimeter = 2(16 1/2 + 12 2/3)

=> 2(16/2+38/3>

=> 2(8+12.6)

=> 2(20.6)

=>41.2 cms

therefore perimeter of rectangle =41.2cms

Answer 2

Answer:

$\frac{175}{3} cm$

Step-by-step explanation:

perimeter of rectangle = 2(l+b)

$2(16 \times \frac{1}{2} + 12 \times \frac{2}{3} )$

$2( \frac{33}{2} + \frac{38}{3} )$

$2( \frac{99 + 76}{6} )$

$2 \times \frac{175}{6}$

$\frac{175}{3} \: cm$
