Question

Manju runs around a rectangular park of
length 35 m and breadth 20 m. Meenu runs
around a square park of side 30 m. Who covers
less distance and by how much, if Meenu takes
4 rounds and Manju takes 3 rounds completely.
(a) Meenu, 150 m
(b) Manju, 120 m
b) Manju, 150 m
(d) Meenu, 120 m​

Answer 1

Answer:

  1. Distance ran by Manju ( Rectangle )

l = 35 m

b = 20 m

Perimeter of Rectangle = 2 (l+b)

                                       = 2(35+20)

                                       =  2(55) = 110 m

Distance she ran after 3 rounds = 3(110 m) = 330 m

2. Distance ran by Meenu (Square)

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

Perimeter of Square = 4s

                                 = 4(30) = 120 m

Distance she ran after 4 rounds = 4(120 m) = 480 m

3. Difference in their distance = 480 m - 330 m = 150 m

Therefore Manju ran less distance than Meenu by 150 m
