Question

Mera 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

hi friend
here's your answer looking for

to find the total distance travelled by Mira, first we have to find the perimeter of that rectangular park.

so, perimeter of the rectangular park = 2(l+b)

so, perimeter =
$2(l + b) \\ \\ = 2(140 + 19) \\ \\ = 2 \times 159 \\ \\ = 318m$
so,

distance travelled by her after completing 5 round is

$(5 \times 318)m \\ \\ = 1590m$

so, this is your answer

hope you are satisfied with my answer

Answer 2

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!!
