Floor

A room has a floor area of 33 m² and a width of 4 m. What is the perimeter of the room as shown on a map at scale 1:75, measured in centimetres?

Final Answer:

o =  32.7 cm

Step-by-step explanation:

S=33 m2 a=4 m M=75  S = a b b=S/a=33/4=433=8.25 m  o1=2 (a+b)=2 (4+8.25)=249=24.5 m o2=o1 cm=o1 100  cm=24.5 100  cm=2450 cm  o=o2/M=2450/75=32.7 cm
