Question

a square paper sheet has 10 hole 2/5 cm long wide. find its perimeter and area.

Answer 1

Appropriate Question:-

A square paper sheet is 10 whole 2/5 cm long wide. Find its perimeter and area.

━━━━━━━━━━━━━━━━━━━━━━━━━

Given:-

• A square paper sheet is $10\dfrac{2}{5}cm$ long wide.

To Find:-

• It's Perimeter and Area

Formula Used:-

• ${\boxed{\bf{Perimeter\:of\:Square=4\times Side}}}$

• ${\boxed{\bf{Area\:of\:Square= Side^2}}}$

Solution:-

Using,

$\bf :\implies\: Perimeter\:of\:Square=4\times Side$

Here,

• Side = $\bf 10\dfrac{2}{5}$ = $\bf \dfrac{52}{5}$cm

Putting value,

$\sf :\implies\: Perimeter\:of\:Sheet=4\times \dfrac{52}{5}$

$\sf :\implies\: Perimeter\:of\:Sheet=\dfrac{208}{5}$

$\bf :\implies\: Perimeter\:of\:Sheet=41.6\:cm$

Now Using,

$\bf :\implies\: Area\:of\:Square= Side^2$

$\sf :\implies\: Area\:of\:Sheet= (\dfrac{52}{5})^2$

$\sf :\implies\: Area\:of\:Sheet= 10.4^2$

$\bf :\implies\: Area\:of\:Sheet= 108.16\:cm^2$

Hence, The Perimeter and Area of the square paper sheet is 41.6cm and 108.16cm² respectively.
