Answer:
f(2) = 28
Step-by-step explanation:
![\rm f(x) = 8 {x}^{2} + 4x - 12](https://tex.z-dn.net/?f=%20%5Crm%20f%28x%29%20%3D%208%20%7Bx%7D%5E%7B2%7D%20%20%2B%204x%20-%2012%20)

The answer would be 1952 because the display of flag makes a right triangle so we will use Pythagorean theorem in order to find the sides and the sides total is 244 according to theorem, so we multiply by 8 to get the 8 flag display. <span />
