Understanding Scaled Drawings

What is a scaled drawing?

• A drawing that is larger than the actual object.

• A drawing that is smaller than the actual object.

• A drawing that maintains the proportions of the actual object.

• A drawing that is not proportional to the actual object.

If the actual dimensions of the kitchen are 24 ft. by 24 ft., what is the scale of the drawing?

• 1cm : 9ft

• 1cm : 8ft

• 4cm : 1ft

• 1cm : 4ft

If a scale of 1:50 is used in a drawing, what does this mean?

• 1 unit on the drawing is equal to 50 units in real life.

• 50 units on the drawing is equal to 1 unit in real life.

• The drawing is 50 times larger than the actual object.

• The drawing is 50 times smaller than the actual object.

What is a scale factor?

• A scale factor is a multiplier used to resize an object.
• A scale factor is used to calculate area only.
• A scale factor is a fixed value that cannot change.
• A scale factor is a type of measurement unit.
