Answer:

200m is the length

Step-by-step explanation:

l = 2b

5 x Perimeter = 3000m (3km)

5 x 2 ( l + b) = 10 x ( 2b + b) = 3000

3b = 3000/ 10= 300

b = 300/3 = 100m

Breadth= 100m

Therefore length is 2x100= 200m

Answer:

Here,

  • Let the breadth be x

[ Now , according to question ⤵]

  • So , the length will be 2x

  • Its given she jogged 5 times of the field n in overall covered a distance of 3Km
  • Therefore, perimeter will be 3Km /5 OR 3000m /5

Now ,

We use the formula of perimeter to find the length and the breadth ;

Perimeter = 2 × ( length + Breadth )

3000/5 = 2 × ( 2x + x )

600 = 4x + 2x

600 = 6x

x = 600/6

x = 100

Hence ,

  • We assumed breadth as x ,so breadth = 100m

  • We assumed length as 2x , so length = ( 2 × 100) => 200 m

Therefore , the Length is 200 m and the breadth is 100 m.
