Answer:

Rs. 1950

Step-by-step explanation:

If the two roads are parallel to length and breadth, then the length of the park is the length of 'road A', and the breadth of the park is the length of 'road B'

Area of Road A:

= L x B

= 36m x 2.5m

= 90 $m^{2}$

Area of Road B:

= L x B

= 24m x 2.5m

= 60 $m^{2}$

Cost of COnstructing the road:

= Rs13 x (Total Area)

= 13 x (60+90)

= 13 x 150

= Rs 1950
