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

Answer»

nSwer :-

\longrightarrow \sf \:<klux>2</klux> \times (12 \frac{1}{2} + 10 \frac{2}{3}) \\

\longrightarrow \sf \:2 \times ( \frac{25}{2} + \frac{32}{3} ) \\

LCM of 2 and 3 is 6.

\longrightarrow \sf \:2 \times ( \frac{25 \times 3}{2 \times 3} + \frac{32 \times 2}{3 \times 2} ) \\

\longrightarrow \sf \:2 \times ( \frac{75}{6} + \frac{64}{6} ) = 2 \times ( \frac{75 + 64}{6} ) \\

\longrightarrow \sf \frac{139}{6} = <klux>23</klux> \frac{1}{6} \\

Therefore,the perimeter of the rectangle is 23 1/6 CM.
