B In a new scale drawing of the same room, the length of the room measures 4 inches. What is the scale of the new drawing? Explain

Answer 1

1 foot length in the scale drawing means 36 feet for the room's actual length

6 inches = 1/2 foot

1/2 to 18 feet is the same as 1 foot to 36 feet

(1/2)/18 = 1/36

the scale is 1:36

the room length is 36 times the scale drawing length

4 inches is 1/3 of a foot

1/3 to 18 is (1/3)/18 = 1/48. scale is 1:48

the room length is 48 times the scale drawing length
