Question

Shilpa takes 2 rounds along a square park of side 135m and Rimpy takes 4 rounds a
rectangular park with length 75 m and breadth 40m who covers more distance and by
how much?​

Answer 1

Answer:

Step-by-step explanation:

shilpa takes 2 rounds along a square park of side 135m

so she is running along the perimeter ( boundary ) of a square

perimeter of a square = 4 x length of side

= 4 x 135

= 540 metres

so distance covered in 1 round = 540 metres

but Shilpa ran 2 rounds

so she covered 540 x 2

= 1080 metres

so shilpa covered 1080 metres totally

Rimpy takes 4 rounds a  rectangular park with length 75 m and breadth 40m

so Rimpy is running along the perimeter ( boundary ) of a rectangle

perimeter of a rectangle  = 2 ( Length + Breadth )

= 2 ( 75 + 40 )

= 2 x 115

= 230 metres

but rimpy ran 4 rounds

so distance covered by rimpy = 4 x 230

= 920 metres

so rimpy covered 920 metres totally

we find that shilpa ran more distance than rimpy because shilpa ran 1080 metres and rimpy ran 920 metres

1080 > 920

distance shilpa covered more than rimpy =

distance covered by shilpa -  distance covered by rimpy

= 1080 - 920

= 160 metres

hence, shilpa ran more distance than rimpy and by 160 metres.
