Answer: 997.50
Step-by-step explanation:
Total area of plain wall = (10*3)*2 + (8*3)*2 = 108 sqm
Total area of doors = (2*1.5)*2 = 6 sqm
Total area of windows = (1*0.75)*3 = 2.25 sqm (∴1cm = 0.01m)
Then,
Total area of wall = 108-6-2.25 = 99.75 sqm
Now,
Total cost of distempering = 99.75*10 = Rs. 997.50
