Question

find the distance travelled by Saina if she takes 3 round of a square Park of side 70 metre​

Answer 1

$\bf{\underline{\underline \blue{Solution:-}}}$

$\sf\underline{\red{\:\:\: AnswEr:-\:\:\:}}$

• Distance covered in 3 rounds = 840 metre

$\sf\underline{\red{\:\:\: Given:-\:\:\:}}$

• Saina takes 3 round of a square Park of side 70 metre.

$\sf\underline{\red{\:\:\: Need\:To\: Find:-\:\:\:}}$

• Distance covered in 3 rounds = ?

$\sf\underline{\pink{\:\:\: Diagram:-\:\:\:}}$

$\setlength{\unitlength}{20} \begin{picture}( 0 , 0 ) \put( 1 , 1){ \line( 0 , 1){4}}\put( 1 , 1){ \line( 1 , 0){4}}\put( 5 , 1){ \line( 0 , 1){4}}\put( 1 , 5){ \line( 1 , 0){4}}\put(2, 0.5){ \tt{\:\:70\:\: metre} } \end{picture}$

$\textbf {Side of square park = a = 70 metre}$

$\textbf {Perimeter of park = 4 a}$

$\dashrightarrow \sf {Perimeter\:of\:park = 4 \times 70}$

$\dashrightarrow \sf {Perimeter \:of\:park = 280\:Metre}$

$\sf\underline{\red{\:\:\: Now:-\:\:\:}}$

• Saina takes 3 rounds of the square park.

$\bigstar \: \boxed{ \sf \:Distance\: travelled = 3 \times Perimeter\: of \:park}$

$\dashrightarrow \sf {Distance \: travelled = 3 \times 280\:metre}$

$\dashrightarrow \sf {Distance \: travelled = 840 \:metre}$

$\sf\underline{\red{\:\:\: ThereFore:-\:\:\:}}$

• Distance covered in 3 rounds is 840 metre.

Answer 2

Given :

Side of square park = 70 metre

Sania takes 3 rounds of square park

To Find :

Distance travelled by Sania

Solution :

Perimeter of square park = 4a

=> 4×70

=> 280m

According to question :

Sania takes 3 rounds of square park

So

Distance travelled by sania = 3×280 = 840m

Formula Used :

Perimeter of square = 4× side of square

Thus, 840m is the required answer.
