Answer:
The perimeter of the image is 144 inches
Step-by-step explanation:
we know that
If two figures are similar, then the ratio of its perimeters is equal to the scale factor
so
The perimeter of the image is equal to the perimeter of the pre-image multiplied by the scale factor

Easiest way to get the surface area of the lateral square pyramid is by using the formula:
![A_{L} = a \sqrt{ a^{2}+4 h^{2} }](https://tex.z-dn.net/?f=A_%7BL%7D%20%3D%20a%20%5Csqrt%7B%20a%5E%7B2%7D%2B4%20h%5E%7B2%7D%20%20%7D%20)
a = Base edge = 646 ft
h = Height = 350 ft
Using the formula:
![A_{L} = 646 \sqrt{ 646^{2}+4 350^{2} }](https://tex.z-dn.net/?f=A_%7BL%7D%20%3D%20646%20%5Csqrt%7B%20646%5E%7B2%7D%2B4%20350%5E%7B2%7D%20%7D%20)

[tex]A_{L} = 615335<span> square feet</span>
Velocity is speed. It doesn't matter what direction.
