Question

14.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
to.) Manju, 150 m
(d) Meenu, 120 m​

Answer 1

Answer:

c) Manju 150m

Step-by-step explanation:

Manju runs around a rectangular park of dimensions:

Length=35m

Breadth=20m

She runs around the rectangular park so she covers the perimeter of that park

Perimeter of rectangular park = 2(L+B)

=2(35+20)

=2(55)

=110m

She takes 3 rounds so 110*3= 330m

Meenu runs around a square park of side 30 m

Perimeter of square = 4*side

= 4*30

= 120m

She takes 4 rounds so 120*4= 480m

So, it's clear that manju covers less distance by (480-330) = 150m
