Question

Manju runs around a rectangular Park of length 35 M and breadth Park of side 30 who covers less distance and by how much if Meenu takes 4 rounds and manju takes 3 rounds completely ​

Answer 1

Answer:

Manju covers less distance and by 150 m

Step-by-step explanation:

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

Answer 2

Solution:

Distance covered by manju = Perimeter of a square park

Perimeter of square = 4 x side

= 4 x 75 = 300 m

Thus, the distance covered by manju is 300 m.

Now, distance covered by meenu = Perimeter of rectangular park

Perimeter of rectangular park = 2 x (length + breadth)

= 2 x (60 + 45)

= 2 x 105 = 210 m

Thus, meenu covers the distance of 210 m.

And meenu covers less distance.
