Respuesta :

Answer:

  100 m

Step-by-step explanation:

Lalith purchased a total of 8 × 20m = 160 m of wire for ₹800, so paid ...

  (₹800)/(160 m) = ₹5/m

Shekhar paid ₹800 -300 = ₹500 less, so must have purchased ...

  (₹500)/(₹5/m) = 100 m

less wire.

The difference between the field perimeters is 100 m.
