solusion

⟼Painting of the wall has to be done excluding the area of the door.

⟼Area of the door = 1xb

⟼= 3 x 2 m² = 6 m2

⟼Area of wall including door = side x side

⟼ = 10 m x 10 m = 100 m2.

⟼Area of wall excluding door = (100 -6) m²

= 94 m².

⟼Total labour charges for painting the wall = 32.50 x 94 = 235rupees.
