Question

The length of a rectangular field is twice its breadth .Arjun jogged around it 3 times and covered a distance of 5.4 km find the length and breadth of the field

Answer 1

Answer:

Step-by-step explanation:

Let breadth be l

" length be b

ATQ,

Length=2(breadth)

L = 2b ----------(1)

Arjun takes 3 rounds and cover distance =5.4km

Distance in m will be 5400m

Now distance travel in one round =5400/3

=1800m

One round= perimeter of rect.

1800 = 2(l+b)

We know that l=2b (from 1)

.: 1800 =2(2b+b)

1800 =6b

b=300m

Breadth =300m

Now

Length =2 breadth

Length = 2×300

=600 m

.: length =600m and breadth=300m
