Let altitude of rhombus be x meter

So, base= 3x meter

Rate of cultivating field= ₹2800 per hectare

Total cost of cultivating= ₹33,600

Therefore, Area of field = 33600/2800

hectares

= 12 hectares

= 120000m²

Now,

3x²= 120000

So x²= 40000

x²= (200)²m²

x=200m

Base(Side) of Rhombus = 3× 200m

= 600m

Perimeter of field= 4×600

= 24000m

Length of required barbed wire fence the field twice= 2×2400m = 4800m
