Question

Two cross roads, each of width 5 m, run at right angles through the
centre of a rectangular park of length 80 m and breadth 40 m and
parallel to its sides. Find the area of the roads. Also find the cost of
levelling the roads at the rate of Rs. 50 per m2. ​

Answer 1

Answer:

area of the roads : 575 sq.m

cost of leveling : 28750 ₹

Step-by-step explanation:

80×5 = 400

(40-5)×5 = 175

addition of both area will give the total area :

575 sq.m

the cost per m. multiplied by the total area will give the total amount required :

575×50=2625

the total cost is 2625 ₹
