Question

Pinky runs around a square field of side 75m, Rosy runs around a rectangular field with length 160m and breadth 105m. Who covers more distance by how much? plz plz answer for this question plz.....​

Answer 1

Given :

• Pinky runs around square field of side 75 m.

• Bob runs around rectangular field of length 160 m and breadth 105 m.

To Find :

• Who covered more distance and by how much?

Solution :

We have to find who covered more distance, so first of all, we have to find the perimeter of both the fields.

Therefore, distance covered by Pinky will be perimeter of square field :

Now, for perimeter of square, we have :

$\large \underline{\boxed{\bf{ Perimeter = 4 \times side }}}$

$\sf : \implies Perimeter = 4 \times 75 \: m$

$\sf : \implies Perimeter = 300\:m$

$\large \underline{\boxed{\bf{ Perimeter = 300\:m}}}$

Hence, Pinky covered 300 m.

Now, distance covered by Rosy will be perimeter of rectangular field :

Now, for perimeter of rectangle, we have :

$\large \underline{\boxed{\bf{ Perimeter = 2(length + breadth)}}}$

$\sf : \implies Perimeter = 2(160\: m +105 \: m)$

$\sf : \implies Perimeter = 2 \times 265 \: m$

$\sf : \implies Perimeter = 530\:m$

$\large \underline{\boxed{\bf{ Perimeter = 530\:m}}}$

Hence, Rosy covered 530 m.

As, 530 m > 300 m

Therefore, Rosy covered more distance than Pinky.

Difference = 530 m - 300 m

Difference = 230 m

Therefore, Rosy covered 230 m more than Pinky.
