The diagram is in the attachment ⤴️
We know that,
Area of a square = (side)²
Cost of Cementing = Area of ABCD-Area of PQRS
Area of ABCD=(side)²
= (40)²
= 1600 m²
Area of PQRS= (side)²
= (35)²
= 1225
Cost of Cementing = Area of ABCD-Area of PQRS
Cost of Cementing= 1600-1225
Cost of Cementing= 375×50
Cost of Cementing= ₹18750
So, the cost of Cementing is ₹18750
