Answer 2

Answer:441m²,₹48510

Step-by-step explanation:

length of the field = 90m

breadth of the field = 60m

from the diagram:

AD = SP = RQ = BC = 90m,

AB = HG = EF = CD = 60m

the width of the roads = 3m

so the area of the roads = (90 × 3)+(60×3)-(3×3)

= 270 + 180 - 9

441 m²

rate of cost = ₹110/m²

so total cost = ₹(441 × 110)

= ₹48510
