Step-by-step explanation:

a door length = 1 m

breath= 3 m

perimeter of rectangle =

= 2 ( l + b )

= 2 ( 1 + 3 )

= 2 ( 4 )

= 8 m

length of wall = 6m

breath = 7.5m

area of rectangle

= length x breath

= 6m x 7.5m

= 45m²

cost of white washing the wall per m² = 100

cost of white washing the walk 45 m²

= 45 m² x 100

= 4500 m²

hope it helps
