Question

A rectangular plot 200m *150m has three 3 m wide road Along the length of the plot on other side and one in to the middle. On either side of the middle road there are shops

Answer 1

Answer:

Length of plot, a = 200

Breadth of pot, x = 150

Total area of plot = a * x = 200 * 150 = 30000 m2

Length of single road , l = length of plot = 200

Breadth of single road , b = 3

Area covered by 3 roads = 3 * l * b = 1800 m2

Area covered by shops =  Area covered by plot  - Area covered by 3 roads  = 30000 - 1800 = 28200 m2

Rate of constructing roads  = Rs. 225 / m2

Total cost of constructing 3 roads = 225 * Area covered by 3 roads = 225 * 1800

= Rs. 405000

have a good day :)
