Question

the length of a rectangle field is twice it's breadth. meghna jogged around it 5 times and covered a distance of 3 km What is the length of the field​

Answer 1

Answer:

200m

Step-by-step explanation:

Meghana jogged around a rectangular field 5 times and covered a distance of 3 km.

So, the perimeter of the field is 3000/5 = 600 m.

The sum of adjacent sides = 600/2 = 300 m.

Length, L = 2x breadth, or 2B

B+2B = 3B = 300 m, or

B = 100 m and L = 200 m.

Check: (100+200) x 2 x 5 = 300 x 2 x 5 = 3000 m = 3 km. Correct.

Length, L = 200 m.

Hope it helps....
