Answer:
D) 4.45 m by 6.82 m
Explanation:
The given dimensions of the floor plan are 4.9 cm by 7.5 cm.
Given scale factor = 0.011
⇒ 0.011 m = (0.011 × 100) cm = 1.1 cm
Therefore, every 1.1 cm on the plan equals 1 m in the actual room.
To find the dimensions of the actual room in meters, divide the floor plan dimensions by 1.1:
⇒ 4.9 ÷ 1.1 = 4.45 m (2 d.p.)
⇒ 7.5 ÷ 1.1 = 6.82 m (2 d.p.)
