Question

Rinky runs around a square field of side 70 while Pinky runs around a rectangular field with length 90m mand breadth 60m who covers more distance and by how much​

Answer 1

Rinky: covers perimeter of square field

=70 x 4 = 280 m

Pinky: covers perimeter of rectaangular field

=2x(90+60) = 150x2=300m

therefore pinky covers more distance than rinky by (300-280)=20m

Answer 2

Answer:

Step-by-step explanation:

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 = 300 m

Therefore, Pinky ran a distance of 300 m.

Perimeter of the Rectangular field:

Formula: 2 (Length + Breadth)

Substituting the values in the formula,

Perimeter = 2(160 + 105)

Perimeter = 2 x 265

Perimeter = 530 m

Therefore, Bob ran a distance of 530 m.

∵ 530 cm > 300 m

Now in comparison, Bob ran more distance.

By how much = The difference.

530 - 300 = 230 m.  

Therefore, Bob ran more distance than Pinky by 230 m.

Hope it helps!
