Question

A rectangular field is 72 m by 58 m. Amar walks
round it at the rate of 3 km per hour. What time
will he take in taking 2 rounds.​

Answer 1

Answer:

First, find the perimeter of the rectangle..

Perimeter = 2(l+b)

= 2(72+58)

= 2 x 130

= 260m

2 rounds = 260 x 2 = 520m = 0.52km

Speed of Amar = 3km/hr

Time taken = Distance x Speed

==> 0.52 x 3

== 1.56hrs

Answer 2

1.56 hours
Hope it helps
