Question

a door of length 5m and breadth 2m is fitted in a wall the length of the wall is 6.5m and breadth 4.5m find the cost of washing the wall if the rate of white washing the wall is rs 50 per meter square

Answer 1

Door:
L=5m
B=2m
Area=l×b
=10m^2
Wall:
L=6.5m
B=4.5m
Area= area of the wall-area of the door
=29.25m^2-10m^2
=19.25m^2
So,1m^2=50/-
19.25m^2=19.25m^2×50
=962.5/-
