Question

A rectangular sheet of paper is 14/3 cm long and 17/2 cm wide. Find its perimeter.​

Answer 1

Length = 12\frac{1}{2}cm\ =\ \frac{25}{2}cm\1221cm = 225cm Breadth = 10\frac{2}{3}cm=\frac{32}{3}cm1032cm=332cmPerimeter = 2 x (Length + Breadth)= 2\ \left(\frac{25}{2}+\frac{32}{3}\right)\ =\ 2\left(\frac{\left(25\ \times\ 3\right)+\left(32\ \times2\right)}{6}\right)\ =\ 2\left(\frac{75+64}{6}\right)\2 (225+332) = 2(6(25 × 3)+(32 ×2)) = 2(675+64) =\ 2\ \times\frac{139}{6}=\frac{139}{3}=46\frac{1}{3}cm= 2 ×6139=3139=4631cm
