Question

Rahul and Shweta are health conscious. Rahul on morning walk takes 5 rounds of a rectangular park measuring 80 m long and 75 m wide. Shweta goes for evening walk and complete 4 rounds of a square shaped garden with side 80 m. Who covers more distance and how much? the answer in my answersheet is rahul 270m​

Answer 1

Answer:

Step-by-step explanation:

Perimeter of the rectangular park(In which Rahul takes round)

= 2(80+75)= 310m

Perimeter of the square park(in which shweta takes round)

=4(80) = 320m

Clearly,310m<320m    

Thus, swetha covers more distance by 10m

Answer 2

Answer:

Rahul covers more distance by 270 m.

Step-by-step explanation:

Length of the rectangular park=80 m

Breadth of rectangular park=75 m

Perimeter= 2(l + b)

= 310 m

Side of garden= 80 m

Perimeter= 80 x 4 = 320 m

Distance Rahul covers= 310 x 5 = 1550 m

Distance Shweta covers= 1280 m

∴1550 - 1280 =  270m

Hope this helped :)) The answer in your book is correct.
