Question

A rectangular sheet of paper is 12×1/2 cm long and 10×2/3 cm wide. Find its perimeter.

Answer 1

Dimensions of rectangular paper:
l=12*1/2=12/2cm
b=10*2/3=20/3cm
Perimeter =2(l+b)
=2(12/2+20/3)

$= 2( \frac{36+ 40}{6} )$
$= 2( \frac{76}{3})$
=2*12.6
=25.3cm

Answer 2

A rectangular sheet of paper is 12×1/2 cm long and 10×2/3 cm wide.

length = 25/2 cm

breadth = 32/3

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