Since the problem is not telling us the height of Silvio, we are going to assume it is not relevant for our calculations.
Let
the altitude of the incoming plane. We know for our problem that the distance between Silvio and the tower is 3 miles, Also we know that the angle of elevation to the plane is 40°. With this information we can create a triangle as shown in the figure. We need a function that relates the angle of elevation with its opposite and adjacent sides, that function is tangent.
We can conclude that we should use the trig function tangent to model this situation; also, we can conclude that the equation that describes this situation is.

<h2>AREA</h2>
The formula for finding area of a square is:
In a square, all the sides are the same. Each side is 6 meters long. Plug in 6 to the formula.
Multiply:
The area of the square is 36 m²
<h2>PERIMETER</h2>Perimeter is the distance around a shape. To find perimeter, you have to add all all the side lengths. The formula for finding perimeter is:
Remember that squares have 4 sides, and all length(s) and width(s) measure the same. The length and width measure the same. Plug in the numbers into the formula:
Simplify:
Add:
The perimeter of the square is 24 m
By the divergence theorem, the flux across the boundary of the given region
