Step-by-step explanation:

GIVEN -

DIMENSIONS OF THE DOOR = 2M,1M

DIMENSIONS OF THE WALL = 5.4M,3.2M

PAINTING RATE = 150/M^2

WHAT WILL BE THE TOTAL COST OF PAINTING ???

AREA OF DOOR =

$2 \times 1 = 2 {m}^{2}$

AREA OF THE WALL =

$5.4 \times 3.2 = 17.28 {m}^{2}$

now subtract the area of door from area of the wall =

$17.28 - 2 = 15.28 {m}^{2}$
