Question

13. A rectangular plot of land is 300 m long and 250 m broad. It has two roads, each 4 metres wide
running midway within it one parallel to the length and the other parallel to the breadth. Find the
area of the roads. Also calculate the cost of constructing the roads at 50 per square metre.​

Answer 1

Answer:

area of road along the length = 4×300 = 1200 m²

area of road along the breadth = 4×250 = 1000 m²

in the middle, the road intersects,  

area of common part = 4×4 = 16 m²

so total area of road = 1200 + 1000 - 16 =2184 m²

cost = Rs 50×2184 = Rs 109200
