Question

6. The length of a rectangular field is twice its breadth. A girl jogged around it 4 times and
covered a distance of 4.5 km. What is the length of the field​

Answer 1

Answer:

1 km =1000 m

so, 4.5 km= 4500 m,

Let breadth of field is x,

so length =2x,

according to question

4×2(2x+x)=4500 m,

8×3x=4500 m,

24x=4500 m,

x=4500/24 m,

x=187.5 m,

so, 2x=2×187.5 m,

2x=375 m

Ans: Lenght of field is 375 m.
