Answer:
Cost of Cementing = 18750 Rs
Step-by-step explanation:
Area of Square = Side × Side
Area of bigger square = 40× 40 = 1600 sq cm
Area of smaller square = 35×35 = 1225 sq cm
Area of cementing = Area of bigger square - Area of smaller square
= 1600 - 1225 = 375 sq cm
Cost of Cementing = 375 × 50 = 18750 Rs
