Answer 1

Answer:

=284rs

Step-by-step explanation:

Dimensions of the door..

length=2m

breadth=1m

Area of door=2*1=2m2

Dimensions of the wall

length=4.5m

breadth=3.6m

Area of the wall=4.5*3.6=16.2m2

Area for white washing =area of the wall-area of the door

=1622-14.2m2

give cost per m2=20rs

Cost of white washing=14.2*20=284rs
