If the remaining part of the wall is to be painted at rate ₹ 12 per sq. M, how much does it cost?
1 answer:
Answer:
₹996
Step-by-step explanation:
Area painted = area of wall - area of wall posture
Area of a rectangle = length x breadth
= 10.5m x 8.5m = 89.25m^2
Area of a square
length x length
2.5m x 2.5m = 6.25m^2
Area painted = 89.25m^2 - 6.25m^2 = 83m^2
Total cost of area painted = 83m^2 x 12 = 996
