Answer 2

Step-by-step explanation:

Answer:

a) length 12 m and breadth 10 m.

b) 2.5 cm.

Step-by-step explanation:

The ratio of scale of drawing to the floor plan of the house is 1:200.

Hence, the actual lengths in the house are reduced by 200 times in the drawing.

a) If a room in the drawing is measured by 6 cm × 5 cm, then the actual dimension of the room will be (6*200) cm× (5*200) cm

or, 1200 cm× 1000 cm  

or, 12 m× 10 m

Therefore, the actual length and breadth of the room are 12 meters and 10 meters respectively. (Answer)

b) If the actual length is 5 meters (or,500 cm.) then it's reduced dimension in the drawing will be 500/200 =2.5 cm. (Answer)
