Question

What is the perimetre of a rectangle whose length and breadth are 3 1/6 and 2 3/4 cm?

Answer 1

Given:-

• A rectangle of length $3\dfrac{1}{6}cm$ and width $2\dfrac{3}{4}cm$.

To Find:-

• It's Perimeter

Formula Used:-

• ${\boxed{\bf{Perimeter\:of\:Rectangle=2(L+ B)}}}$

Solution:-

Using,

$\bf :\implies\: Perimeter\:of\:Rectangle=2(L+ B)$

Here,

• L = $3\dfrac{1}{6}$ = $\dfrac{19}{6}$cm

• B = $2\dfrac{3}{4}$ = $\dfrac{11}{4}$cm

Putting values,

$\sf :\implies\: Perimeter=2(\dfrac{19}{6}+ \dfrac{11}{4})$

$\sf :\implies\: Perimeter=2\times \dfrac{38+33}{12}$

$\sf :\implies\: Perimeter=2\times \dfrac{71}{12}$

$\sf :\implies\: Perimeter= \dfrac{71}{6}\:cm$

or,

$\sf :\implies\: Perimeter= 11.8\overline{3}\:cm$

Hence, The Area of the Rectangle is 71/6cm or 11.83cm.
