Solution

Length =20m

Breadth =15m

Height =10m

To find:

Total cost to cover the walls

1) Only the walls of the rectangular hall are included when you covered it with the wallpaper, So;

The area of the hall to be covered =2hl+b

=2×1020+15=2×10×35=700m2

2) Rate of covering the wall is 60/m2

Total expenditure = Area × rate

=700×60=42000

The total cost to cover the walls is 42000.
