Question

Pinky runs around a rectangular park with the length90m and breadth 45m while Pankaj runs square park of side 75m.Who covers more distance by how much?

Answer 1

Answer:

Pankaj covered 30 m more than Pinky.

Step-by-step explanation:

Pinky runs around a Rectangular park of -

• Length = 90 m
• Breadth = 45 m

Pankaj runs around a Square park of -

• Side = 75 m

To compare the distance covered by them, we need to find perimeter of the respective parks.

Keep in mind that both Pinky and Pankaj ran around the park only once.

★ Perimeter of Rectangle =

⇒ 2(Length + Breadth)

⇒ 2(90 + 45)

⇒ 2(135)

⇒ 270 m

Perimeter of the rectangular park = 270 m

Pinky covered 270 m.

★ Perimeter of Square =

⇒ Side × 4

⇒ 75 × 4

⇒ 300 m

Perimeter of the square park = 300 m

Pankaj covered 300 m.

★ Comparing the distance covered by both =

• Pankaj = 300 m
• Pinky = 270 m

⇒ 300 > 270

Distance covered by Pankaj > Distance covered by Pinky

Pankaj covered more distance.

⇒ 300 - 270

⇒ 30 m

Pankaj covered more distance by 30 m.

Therefore, Pankaj covered 30 m more than Pinky.

Answer 2

Length of a rectangular park= 90m

Breadth of the park= 45m

Therefore, perimeter of the rectangular park= 2×(90m+45m)

= 2× 135 = 270m

Therefore, Pinky runs around a rectangular park of 270m

Side of a square park= 75m

Therefore, Perimeter= 4×s

= 4×75m

= 300m

Therefore, Pankaj runs around a square park of 300m

Therefore, comparing= 300m, 270m

Therefore, 300m is greater than 270m, Pankaj ran a greater distance

By,

300m-270m

=30m
