Question

Bunty and Bubly go for jogging every morning. Bunty goes around a square park of side 80m and Bubly goes around a rectangular park with length 90m and breadth 60m. If they both take 3 rounds, who covers greater distance and by how much?

Answer 1

Step-by-step explanation:

Bunty:

perimeter of a square=4s

= 4*80=320meters

he took 3 rounds around this squarepark so 320*3= 960m

Bubly:

perimeter= 90+60+90+60=300m

he took 3 rounds so 300*3=900m

Therefore bunty covers more distance

he covers more distance by 60m.

Answer 2

Step-by-step explanation:

bunty goes to a square park

he walks around it's boundary

basically boundary is perimeter

perimeter of square = 4 (side)

side is 80 m

perimeter = 4* 80 =320 m

so, he covers 320 m

bubly walks around the perimeter of a rectangular park

perimeter = 2 ( L + B) = 2 ( 90 + 60 )

= 2 ( 150 ) = 300 m

they both take 3 rounds

distance coverd by bunty

320+320+320= 960 m

distance covered by bubly = 300+300+300 = 900

so, bunty covers larger distance
