The width of the model is 3.6 inches.
The figures with the same shape are said similar when the sides of both the figures are in proportion.
Sara has a model of length = 18inches.
The original ship has a length is 160 ft
The width of the original ship is 32 ft
The model is a scaled-down version of the original figure and so the length and width of the model will be in the same proportion as the original dimensions.
Let x represents the width of the model then,
160/18 = 32/x
x = 32 * 18 / 160
x= 3.6 inches.
Therefore, the width of the model is 3.6 inches.
