no

Answer 2

First let us find area of unshaded portion,
It is a rectangle.
l = 50 m - 3 m = 47 m
b = 43 m - (1+ 2 m) = 43 - 3 m = 40 m
Area of unshaded portion= l*b = 47*40 = 1880 m^2
Cost of polishing unshaded portion = 1880*15 = ₹28,220

Area of shaded portion = Total portion - Area of unshaded portion

Total portion Area:
l = 50 m
b = 43 m
Area = l*b = 50*43 = 2150 m^2

Area of shaded portion = 2150 - 1880 = 270 m^2

So your answer is:
Area of shaded portion = 270 m^2
Cost of polishing unshaded portion = ₹28,220

Hope this helps you!
