Of the isometries, translation is your best tool. The orientation is already correct so rotation is unnecessary, as is reflection.
The area covered by the shadow is given by:
A = (512,000,000) * (0.9 / 100)
A = 4,608,000
Then, since the area is a rectangle we have:
A = (w) * (l)
Where,
w: width
l: long
Substituting we have:
4,608,000 = (w) * (14,500)
Clearing w we have:
w = (4,608,000) / (14,500)
w = 317.7931034
Round to the nearest kilometer:
w = 318 Km
Answer:
The width of such a rectangle would be:
A: 318km
Answer:

Step-by-step explanation:

An expression becomes an equation by adding an equal sign to the end of the expression and if there's a number on the other side of the equation. For example, 4+3 becomes an equation if you put 4+3=7. Or, 4+3=2+5. Good luck!
So basically, 39=H+3 because 39 is the product = H (hectors height) and (+) 3
