Question

Two cross roads, each of the width 5 m, run at right angles through the centre of a

rectangular pack of length 70 m and breadth 35 m and parallel to its side. Find the area of

roads. Also, find the cost of constructing the roads at the rate of Rs 65 per m2

​

Answer 1

Step-by-step explanation:

area of road parallel to length of park =5×70=350

area of road parallel to breadth of park=5×35=175

area of central square (since it is repeated)=5×5=25

therefore area of roads =350+175-25=400

cost of constructing=400×65=26000 rupees
