Question

a rectangular plot measures 300m by200 my. a builder builds 3 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 in to residential plots and sold at the rate of RS 500 per metre square. calculate the total revenue the builders will generate by selling all the plots.

Answer 1

area of all roads =7800
area of rectangular plot =60000
area of remaining place = 60000-7800
=52200
revenue of plots = 500*52200
=rs. 26100000

Answer 2

Answer:

The revenue generated is of Rs 24,500,000.

Step-by-step explanation:

We are given that,

Dimensions of the plot are 300 × 200 meters.

So, Area of the rectangular plot = Length × Width

i.e. Area of the rectangular plot = 300 × 200 = 60,000 m²

Now, there are 3 roads made along the length of the plot having dimensions 300 × 10 meters.

So, Area of the three roads = 3 × Length × Width

i.e. Area of the three roads = 3 × 300 × 10 = 9000 m²

Further, there is one road along the width of the plot having dimensions 200 × 10 meters.

So, Area of the road = Length × Width

i.e. Area of the road = 200 × 10 = 2000 m²

Thus, the total area of the roads = 9000 + 2000 = 11,000 m²

Then, the area left for the residential plots = 60,000 - 11,000 = 49,000 m²

Since, 1 meter square is sold at Rs 500.

Then, 49,000 m² is sold at 49,000 × 500 = Rs 24,500,000

Hence, the revenue generated is of Rs 24,500,000.
