Question

a room of 8m long ,5m broad and 4m high has 2 doors 1.5 m bu 1m and 3 windows each 1.2m bu 80cm. find: the cost of distempering from inside at the rate of rupees 2 per m^2

Answer 1

Answer:

Step-by-step explanation:

Length of room=8m;

width=5m;

height=1.5m;

Total wall area of room=2*(8*1.5)+2(5*1.5);=2*12+2*7.5;

=24+15=39 sq. mtr (Excluding selling+floor)

Area of wall to be painting=total area-area of door -area of window;

Now calculating the area of door=2*1.5=3sq. m.

there are total 2 doors=3*2=6sq.m

area of window=1.2*0.8=0.96 sq. m;

total area to be paining =39-6-.96=32.04 sq. m

Given that per sq. m cost of distemper is=Rs.2

So total cost=32.04*2=64.08
