Answer:
Scale : 1 mm = [tex]\frac{1}{3}\ m[/tex]
Or
Scale : 3 mm = 1 m
Step-by-step explanation:
Let the scale used be 1 mm = 'x' m
Given:
Actual width of kitchen is 12 m.
Length used by Kate in drawing is 36 mm.
So, 36 mm in drawing is equivalent to 12 m in actual.
Therefore, 1 mm in drawing is equivalent to 'x' m in actual.
Taking proportions and solving by cross multiplication, we get
[tex]\frac{36}{12}=\frac{1}{x}\\36x=12\\x=\frac{12}{36}\\x=\frac{1}{3}\ m[/tex]
Therefore, 1 mm in drawing is equal to [tex]\frac{1}{3}\ m[/tex] in actual.
Scale : 1 mm = [tex]\frac{1}{3}\ m[/tex]
Or
Scale : 3 mm = 1 m
