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.

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
