A room is 6 m long, 5 m wide and 4 m high. Only its four walls are to be painted; the ceiling and floor are left alone. A door measuring 2 m by 1.2 m and two windows each measuring 1.5 m by 1 m are not painted. Find the area actually painted, in m².

Question

Accepted Answer

82.6. Area of the four walls = 2(6 + 5) × 4 = 88 m². Door = 2 × 1.2 = 2.4 m²; the two windows = 2 × (1.5 × 1) = 3 m². Painted area = 88 − 2.4 − 3 = 82.6 m².
