Question

A room is 8m long 6m wide find the cost of white washing its ceilings at rp 11 per sqaure

Answer 1

Answer:

Length (l) of room = 8m

Breadth (b) of room = 6m

Area of ceiling = l*b = 8m*6m = 48m^2

Cost of white washing 1m^2 = ₹11

Cost of white washing ceiling = 11*48 = ₹528

Cost of white washing ceiling at ₹11/m^2 = ₹528
