Answer:
16.8
Step-by-step explanation:
Set up a proportion.
w = width and l = length
I would put the length and the width of the model in the first fraction and the length of the actual building on the right.
[tex]\frac{w}{l}[/tex] =[tex]\frac{w}{l}[/tex]
[tex]\frac{7}{58.7}[/tex] = [tex]\frac{w}{140.9}[/tex] Multiply both sides of the equation by 58.7 and 140.9 and you get:
140.9(7) = 58.7x
986.3 = 58.7x Divide both sides by 58.7
16.8023850085 = x I will round to the nearest tenths' place
16.8
