Question

Tammy is inspecting a 5 m : 10 cm scale floor plan for her house. The dimensions of her bedroom in the scale drawing shown below are 6 cm by 5 cm . Calculate the area of Tammy's bedroom in the real world. Answer will be in square meters.

Answer 1

Explanation:

10 cm represents 5 meters in the real world

6 cm represents x meters

cross multiply

10x = 5*6

10x = 30

x = 3 meters so 6cm is equal to 3 meters in length

10 cm represents 5 meters in the real world.

5 cm = y meters

10y = 5*5

10y = 25 m

y = 25/10 meters = 2.5 meters

Area of the room = 2.5 * 3 = 7.5 square meters
