Scale plan

On a 1:150 scale plan, the garden is 20 cm wide and 30 cm long. What is the actual width and length of the garden? (in meters)

Correct answer:

x =  30 m
y =  45 m

Step-by-step explanation:

a=20 cm→ m=20:100  m=0.2 m b=30 cm→ m=30:100  m=0.3 m M=150  x=M⋅ a=150⋅ 0.2=30 m
y=M⋅ b=150⋅ 0.3=45 m
