Question

the length of a rectangular field is twice its breadth a girl job around it 4 times and covered a distance of 4.5 km what is the length of the field

Answer 1

Step-by-step explanation:

4 times the perimeter is 4.5 I'm

So, the perimeter (1 time) will be 4.5/4

L=2B(given)

Perimeter=2(l+b)

=4.5/4

=2(2B+B)

=4.5/4

=6B=4.5/4

=B=4.5/24

=L=2B

=L=2×4.5/24

=L=9/24

=L=3/8 km
