Question

Praveen runs around a square of side 40 m Naveen runs around a rectangle with length 45 M and breadth 40 m. who covers more distance and how much?​

Answer 1

$\red{\bigstar}$$Naveen covers more distance than Praveen and by [tex]\large\leadsto\boxed{\tt\purple{10 \: m}}$

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

• Given:-

Praveen runs around a square of side 40 m.

Naveen runs around a rectangle with length 45 m and breadth 40 m.

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

• To Find:-

Who covers more distance and by how much.

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

• Concept:-

Praveen is running around a square of side 40 m.

Hence, the distance covered by him will be equal to the perimeter of the square.

Also,

Naveen is running around a rectangle with length 45 m and breadth 40 m.

Hence, the distance covered by him will be equal to the perimeter of the rectangle.

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

• Solution:-

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

✯ For Praveen:-

We know, for the perimeter of square,

$\pink{\bigstar}★ \large\underline{\boxed{\bf\green{Perimeter = 4 \times side}}}$

➪ $\sf Perimeter = 4 \times 40$

$★ \large{\bf\pink{Perimeter = 160 \: m}}$

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

Therefore, the perimeter of the square around which Praveen is running is 160 m.

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

✯ For Naveen:-

We know, for the perimeter of rectangle,

$\pink{\bigstar}★ \large\underline{\boxed{\bf\green{Perimeter = 2(l+b)}}}$

➪ $\sf Perimeter = 2(45 + 40)$

➪ $\sf Perimeter = 2(85)$

$★ \large{\bf\pink{Perimeter = 170 \: m}}$

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

Therefore, the perimeter of the rectangle around which Naveen is running is 170 m.

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

✯ Clearly, we can say that Naveen covers more distance than Praveen.

And,

➪ $\sf 170 - 160170−160$

★$\large{\bf\pink{10 \: m}}$

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

Therefore, Naveen covers more distance than Praveen and by 10 m.
