The amount Aisha would pay to paint her living room is £38.50.
The first step is to determine the area of the walls that do not have doors.
Area of a wall = length x width
3 x (2.6 x 3.5) = 27.30 m²
Dimensions of the wall with the door : (2.6m - 2.2m) x (3.5 - 0.8) = 0.4m x 2.7m
Area of the wall with the door : 0.4m x 2.7m = 1.08 m²
Total area of the walls: 27.30 m² + 1.08 m² = 28.38 m²
Number of paint tins needed for the walls : 28.38 / 8 = 3.55 = 4 tins
Cost of the paint tins : (11 x 3) + (0.5 x 11) = £38.50
