Two cross roads, each of width 5cm, run at right angles through the centre of a
rectangular park of length 50m and breadth is 40m and parallel to its sides. Find
the area of the roads. Also find the cost of constructing the roads at the rate of
Rs.120 per m​

Through a rectangular field of length 90 m and breadth 60 m, two roads are constructed which

are parallel to the sides and cut each other at right angles through the centre of the fields. If the

width of each road is 3 m, find,

(1)

(ii)

the area covered by the roads.

the cost of constructing the roads at the rate of Rs 110 per m².
