Pinky runs around a square field of side 75m, Bobby runs around a rectangular field with
length 55m and breadth 45m. Who covers less distance and by how much?
Answers
Given: Side of the square field measure 75m, length of the rectangular field is 160m and the breadth is 105m.
To find: Whether Pinky or Bob ran more distance and the difference.
Answer:
Since it's given that they ran around the field, we will have to calculate the perimeter.
Perimeter of the Square field:
Formula: 4 x Side.
Substituting the value in the formula,
Perimeter = 4 x 75
Perimeter = 300m
Therefore, Pinky ran a distance of 300m.
Perimeter of the Rectangular field:
Formula: 2(Length + Breadth)
Substituting the values in the formula,
Perimeter = 2(55 + 45)
Perimeter = 2 × 100
Perimeter = 200
Therefore, Bob ran a distance of 530m.
Now in comparison, Bob ran more distance.
By how much ⇒ The difference.
530 - 200 = 330m.
Therefore, Bob ran more distance than Pinky by 230m.
Hope it helps :)
