10800

Let rectangular plot's length=x, breadth=y m, then Area=xy=1400 m² ---(i) and
Perimeter=2(x+y)=150 => x+y=75 ---(ii)
From (i) & (ii), x=40, y=35
Area of a path=Area of a outer rectangular plot - Area of a plot excluding path
=1400 - (40-3)*(35-3)
=1400 - 37*32
=216 m²
So rate of construction=216*50=10800
