Question

find the perimeter of a rectangle whose length is 7 2/5 breath is 3/8 cm ​

Answer 1

Step-by-step explanation:

$Given\begin{cases} In\:a\:rectangle \\ Length={\dfrac {2}{5}} \\ Breadth={\dfrac {3}{8}}\end {cases}$

To find:-

The perimeter of the rectangle

Solution:-

As we know that in a rectangle

${\boxed{Perimeter=2 (Length+Breadth)}}$

• Substitute the values

${:}\longmapsto$$Perimeter=2 ({\dfrac {2}{5}}+{\dfrac {3}{8}}$

${:}\longmapsto$$Perimeter=2 ({\dfrac{16+15}{40}})$

${:}\longmapsto$$Perimeter={\cancel {2}}×{\dfrac {31}{{\cancel{40}}}}$

$\therefore$${\underline{\boxed{\bf {Perimeter={\dfrac {31}{20}}cm}}}}$
