3Arectangular plot measures 300 m by 200 m. A builder builds three roads 10 m wide along the length on either side and one in the middle. He also builds one 10 m wide road in the middle along the breadth. The remaining area is cut into residential plots and sold at the rate of 500 per m. Calculate the total revenue the builder will generate by selling all the plots.

Area of three roads along the lenght=3 (L×B)
= 3(300×10)
=3×3000
=9000meter spuare
Area of road along the breadth=L×B
=200×10
=2000m^2
Area of rectangular field=L×B
=300×200
=60000m^2
Area of plot =60000-(9000+2000)
=60000-11000
=49000m
Area of square made by road along the breadth=
side×side
=10×10
=100m^2
Total area of roads=(2000+9000)+100
=11000+100
=11100m^2
Area of total plot=49000-11100
= 37900m^2
Hence, total cost of solding plots for 500 rupees =37900×500
=RS 18950000....
