Sam wants to make a sketch of the white house with a scale factor of 2 inches to 15 feet. She knows that the white house is about 85 feet wide and 152 feet long. What will the width and height of her model be?

Respuesta :

Answer: The width of the model = 11.33 inches and the height of the model = 20.27 inches.

Step-by-step explanation:

Given: Scale factor:  2 inches in model =  15 feet in actual.

White house is about 85 feet wide and 152 feet long.

Width of model = [tex]\dfrac2{15}\times85=\dfrac{34}{3}=11.33\text{ inches}[/tex]

Height of model = [tex]\dfrac{2}{15}\times152\approx20.27\text{ inches}[/tex]

Hence, the width of the model = 11.33 inches and the height of the model = 20.27 inches.
