Answer 1

Answer:

answer is 70000

Step-by-step explanation:

first multiply 40 and 35 and then by 50

Answer 2

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
