Question

The length of a rectangular sheet of paper is 12 1/2 cm and its breadth is 10 2/3 cm find its perimeter the answer please

Answer 1

we know that the perimeter of any rectangular shaped thing is 2( length + breadth )




given,
length = 12 1 / 2 cm = 25 / 2 cm
breadth = 10 2 / 3 cm = 32 / 3 cm




Now, Applying formula

$perimeter \: = 2( \frac{25}{2} + \frac{32}{3} ) \: cm \\ \\ \\ \\ perimeter \: = 2( \frac{75 + 64}{6} )cm \\ \\ \\ \\ perimeter \: = 2 \times \frac{139}{6} \\ \\ \\ \\ \\ perimeter \: = \frac{139}{3} \: cm$

Answer 2

Length of rectangular sheet = 12 1/2 = 25/2



And,


Breadth of rectangular sheet = 10 2/3 = 32/3 cm.


Perimeter of rectangular sheet = 2 ( L + B )



=> 2 ( 25/2 + 32/3 ) cm



=> 2 ( 75 + 64/ 6 ) cm



=> 2 × 139/6 cm

=> 139/3 cm
