Question

Kendall is building a model sailboat the sail of the actual boat is 6 m tall and 4.5 m wide kendall is making the sail on the model 20 cm tall

Answer 1

The actual dimension of the sail are 6 m tall and 4.5 m wide.

The model is 20 cm tall. First we need to find the ratio which Kendall used in his model.

6 meters of actual length is represented in model by 20 cm.

6 meters of actual length is represented in the model by 0.2 m.

1 meter of actual length is represented in the model by 0.2/6 = 1/30 meters

So, the ratio of actual measure to model measure will be:

1 : 1/30

or

30 : 1

The actual width of the sail = 4.5 meters
The width of the sail in the model will be = 4.5 x 1/30 = 0.15 m = 15cm

So, the dimensions of the sail in the model will be 20 cm tall and 15 cm wide.
