Question

A rectangular sheet of paper is 10 1/2 long and 16 2/3 wide find the perimeter

Answer 1

$\underline { \blue { Dimensions \:of \: a \: rectangular \:sheet }}$

$Length (l) = 10\frac{1}{2} \\= \frac{21}{2} \:units$

$and \:Breadth (b) = 16\frac{2}{3} \\= \frac{50}{3} \:units$

$Perimeter \:of \: the \: rectangular \:sheet (P) \\= 2( l + b ) \\= 2 \Big( \frac{21}{2} + \frac{50}{3}\Big) \\= 2 \Big( \frac{63+100}{6}\Big)\\= 2 \times \frac{163}{6} \\= \frac{163}{3} \\= 54 \frac{1}{3} \:units$

Therefore.,

$\red{Perimeter \:of \: the \: rectangular \:sheet}\\\green { = 54 \frac{1}{3} \:units}$
