the titanic was 883 feet long and 175 feet tall.
a. if a model is built to have a scale ratio of 1in : 36ft , how long will the model be?
b. if a model is built to have a scale ratio of 1 in : 22 ft , how tall will the model be?
c. if a model is built to have a ratio of 1: 30 , how tall will the model be?

A. 24.53 inches long

B. 7.95 inches tall

C. 5.83 inches tall

Step-by-step explanation:

Original size of the Titanic was 883 feet long and 175 feet tall.

A. Scale ratio of 1 in : 36 ft.

scale ratio of a model =

Now length =

Let the length of the model be l inches

so length = =

             l   =

                 = 24.52777 ≈ 24.53 inches long.

B. Scale ratio of 1 in : 22 ft.

scale ratio of a model =

Let the model will be h inches tall.

so height = =

             h =

                = 7.954545 ≈ 7.95 inches tall

C. Scale ratio of 1 in : 30 ft.

scale ratio of model =

Let the model will be h inches tall.

so height = =

       h       =

                = 5.83 inches tall.

i think the correct option is the second option.

x = 3 ± √(5+y)
