Question 105

The dimensions of a plot are 200 m x 150 m. A builder builds 3 roads which are 3 m wide along the length on either side and one in the middle. On either side of the middle road, he builds houses to sell. How much area did he get for building the houses?

Answer 1

Given that, dimensions of plot = 200 m x 150 m and width of road = 3 m

$\therefore$ Total area available for houses = Area of total plot - Area of 3 road
$=200\times 150-3\times (3\times 200)[\because$ area of rectangle = $length\times breadth]$
$=30000-1800=28200m^2$
