Answer:

165 inches (= 13.75 feet)

Step-by-step explanation:

given that the scale is 1:60

this means that 1 unit on the drawing equals 60 units in real life

given that the length in the drawing is 2.75 inches, this means that the length in real life

= 2.75 x 60

= 165 inches

= 165/12 feet

= 13.75 feet
Real length =165in

In order to calculate the real length, use scale length multiply the scale factor of it, then divide the scale factor of real length:
Real length = (Scale length) x (Scale ratio)^-1
Scale length =2.75in
Scale ratio = 1/60
Real length = 2.75 X 1/60 =165in
