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?​

Answer 1

Answer :-

• Rosy covered more distance than Pinky by 230m.

Step-by-step explanation :-

To Find,

• Who covers more distance and how much ??

Solution,

Given that,

• Side of a square field which Pinky runs = 75m
• Length and Breadth of the rectangular field in which Rosy runs = 160m and 105m respectively

Figure,

• Refer the attachment.

Therefore,

As we know that,

Perimeter of the square = 4 × a

Where,

• a = side

And given side of the square is 75m, therefore,

➛ Perimeter = 4a

➛ 4 × 75m

➛ 300m ★

Hence, the perimeter of the square is 300m.

As we know that,

Perimeter of rectangle = 2 ( l + b )

Where,

• l = Length
• b = Breadth

And given length and breadth is 160m and 105m respectively, therefore,

➛ Perimeter = 2 ( l + b )

➛ 2 ( 160 + 150 ) m

➛ 2 × 265

➛ 530m ★

Hence, the perimeter of the rectangular field is 530m.

Now, who covered more distance and how much,

We got,

Distance covered by Pinky = 300m

Distance covered by Rosy = 530

Hence, Rosy covered more distance than Pinky, by,

➛ 530m - 300m

➛ 230m

Hence, Rosy covered 230m more than Pinky.

Answer 2

Answer:

$\huge \: required \: answer$

As we know that

Perimeter (rectangle)=2×(l+b)

Perimeter (square)=4×side

Distance covered by pinky:-

Perimeter=4×side

Perimeter=4×75

Perimeter=300m

Pinky covers a distance of 300m

Perimeter=2(l+b)

Perimeter=2(160+105)

Perimeter-2(265)

Perimeter=530m

Rosy covers more distance and by (530-300) 230m.
