Answer 1

Answer:

Dimensions of the door..

Length =2 m

Breadth =1 m

Area of the door =2*1 =2 m²

Dimensions of the wall...

Length =4.5 m

Breadth =3.6 m

Area of the wall =4.5*3.6=16.2 m²

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

=) 16.2-2=14.2 m²

Given cost per m²=20 rs

Cost of white washing =14.2*20=284 rs

This is your answer...
