Question

Meera want to rectangular Park 140 M long and 19 wide she took 5 complete rounds on its boundary what is the distance covered by her.

Answer 1

heya!! 

here is your solution - 

Distance travelled = perimeter of the park

Given, 
length = 140 m 
breadth = 19 m 
Perimeter 
= 2 ( l + b ) 
= 2 ( 140 + 19 ) m
= 2 ( 159 ) m 
= 318 m 

Now, number of rounds = 5 
Total distance covered = 5 × 318 = 1590 m 

hope it helps!!

Answer 2

heya!
here's your answer!
_______________________
_________

as we know,
the park is rectangular.. therefore ,
perimeter of the rectangle = sum of lengths of all sides of the park .

therefore,
given,
length of park= 140m
breath= 19 m

therefore,
perimeter= 2( l + b )
= 2 (140+19)
= 2 x 159
= 3 1 8 m

now, since Meera took five rounds , the distance she covered :-
5 x perimeter = 5 x 318 = 1590 m

Hope this helps you:)
