⇒ 1. Distance ran by Manju (Rectangle) :

• l = 35 cm
• b = 20 cm

$\sf{Perimeter \:of \: Rectangle\: = 2 (l+b)}$

$\:\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \ \: \: \: \: \: \: \: = \sf{2(35 + 20)}$

$\:\: \: \: \: \:\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \ \: \: \: \: \: \: \: = \sf{2(55)}$

$\:\: \: \: \: \: \: \: \:\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \ \: \: \: \: \: \: \: = \sf{110 \: m}$

Distance she ran after 3 rounds :

• $\sf{ = 3 \times 110}$
• $\sf{ = 330 \: m}$

⇒ 2. Distance ran by Meenu (Square) :

• s = 30 m (All sides of a square is equal)

$\sf{Perimeter \: of \: Square = 4 \times S}$

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \sf{= 4 \times 30} \\ \ \sf{ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 120 \: m}$

⇒ 3. Difference in their distance

• = 480 - 330

• = 150 m

✪ Therefore, Manju ran less distance than Meenu by 150 m

so the option is :

C) Manju , 150 m
