Answer:
the dimensions of the drawing scale are
60 units by 20 units
Step-by-step explanation:
Given:
A game room has a floor that is 75 feet by 20 feet
A scale drawing of the floor on grid paper uses a scale of 4 units:5 feet
The length of the drawing scale is
Let actual Length [tex]l = 75[/tex] feet.
actual width [tex]w = 20[/tex] feet.
Drawing [tex]Length=\frac{l}{5} \times 4 units[/tex]
Put the actual length in above equation.
Drawing [tex]Length=\frac{75}{5} \times 4 units[/tex]
Drawing [tex]Length=15 \times 4 [/tex]
Drawing [tex]Length=60 units[/tex]
The drawing length is 60 units.
For drawing width
Drawing [tex]width=\frac{20}{5} \times 4 units[/tex]
Put the actual width in above equation.
Drawing [tex]width=\frac{20}{5} \times 4 units[/tex]
Drawing [tex]width=4 \times 4 [/tex]
Drawing [tex]width=16 units [/tex]
The drawing width is 16 units.
Therefore, the dimensions of the drawing scale are
60 units by 16 units
