A Rectangular sheet of paper is $\displaystyle 12\frac{1}{2} \ cm\ $ and $\displaystyle 10\frac{2}{3} \ cm\ $ wide. Find its Perimeter.
Given :
Length of Rectangular sheet = $\displaystyle 12\frac{1}{2} \ cm\ $
Breadth of Rectangular sheet = $\displaystyle 10\frac{2}{3} \ cm\ $
To Find :
The perimeter of Rectangular Sheet.
Solution :
Formula to find Perimeter of Rectangle = $\displaystyle 2\ ( Length\ +\ Breadth)$
Length = $12\frac{1}{2}=\frac{12\times 2+1}{2} = \frac{25}{2}$ cm
Breadth = $10\frac{2}{3} =\frac{10\times 3+2}{3} =\frac{32}{3}$ cm
$2( Length+Breadth) = 2(\frac{25}{2}+\frac{32}{3})$
Take LCM, LCM of 2, 3 is 6.
$=2(\frac{25\times 3}{2\times 3}+\frac{32\times 2}{3\times 2}$
$=2(\frac{75}{6} +\frac{64}{6})$
$=2(\frac{75+64}{6})$
$=2(\frac{139}{6})$
$=\frac{139}{3}=46\frac{1}{3}$
Perimeter of Rectangular sheet = $46\frac{1}{3} \ cm$.
