Question

a rectengular sheet of paper is 12 1/2 cm long and 10 2/3 cm wide find its perimeter ​

Answer 1

Answer:

$length = 12 \frac{1}{2} \: cm = \frac{25}{2} \: cm$

$breadth = 10 \frac{2}{3} \: cm = \frac{32}{3} \: cm$

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