a boat builer wamts to make a modle of a schooner, a type of sailboatwith at least two masts. the schooner is 34 meters in lengt
BlackZzzverrR [31]
First you should set up fractions equal to each other to see the size ratio

8/34 = x/1.2

As to make comparable fractions. Then you would cross multiply in order to get
34x = 9.6
Divide both sides by 34 and you should get an answer of 0.28m for the model beam.
