Answer:
60 m
Step-by-step explanation:
Perimeter of a rectangle = 2 x width + 2 x length
From inspection of the diagram, the width of the villa is 4 cm and the length is 6 cm
Therefore, perimeter of the villa = (2 x 4) + (2 x 6) = 20 cm
We are told that there is a scale 1 cm : 3 m
This means that 1 cm = 3 m
Therefore, to convert the perimeter found in cm into meters, we need to multiply it by 3:
Perimeter = 20 x 3 = 60 m
