Answer:
Rs. 4400
Step-by-step explanation:
Area of wall = 10 × 10 = 100
Area of door = 3 × 4 = 12
Area to be painted = 100 - 12 = 88
Rate = 88 × 50 = 4400

Answer:
Rs 4400
Step-by-step explanation:
Area of door 12 m^2(3m×4m)
Area of complete wall 100 m^2(10m×10m)
Area to be painted= Area of wall- area of door
100-12=88
Price of per square meter is 50
So total price = 88×50= 4400
