Question

9. Two cross roads each of width 5 m, run through the centre of a rectangular park of
length 75 m and breadth 55 m. Find the area of the paths and the cost of paving
them at the rate of Rs.130 per sq m.​

Answer 1

Answer:

length of the rectangular park=75m

breadth of the rectangular park=55m

width of the road=5m

(area of the roads)=(area of the road 1 +area of the road 2)-(area of the mid square)

(75×10+35×10)-(5×5)

=(750+350)-(25)

=(1100)-(25)

=1075sqm

rate of paving per sq m = rs.130

cost of paving 1075 sq m = 1075×130

=139750rs
