Answer :

(i) It is given in the question that,

Length of field = 90 m

Breadth of field = 60 m

We know that,

Area of rectangle = Length × Breadth

Area of field = 90 × 60

= 5400 m2

Also, we have

Length of road PQRS = 90 m

Length of road ABCD = 60 m

Width of each road = 3 m Area of the roads = Area of (PQRS) + Area of (ABCD) – Area of (KLMN)

= (90 × 3) + (60 × 3) – (3 × 3)

= 270 + 180 – 9

= 450 – 9

= 441 m2

(ii) It is also given in the question that,

Cost of constructing 1 m2 of road = Rs 110

Cost of constructing 441 m2 road = 110 × 441

= Rs 48510
