Answer:
![s(u(2)) = 135](https://tex.z-dn.net/?f=s%28u%282%29%29%20%3D%20135)
Step-by-step explanation:
![u(t) = 7t - 2 \\ u(2) = 7(2) - 2 \\ u(2) = 14 - 2 \\ u(2) = 12 \\ \\ s(t) = {t}^{2} - 9 \\ s(u(2)) = {(12)}^{2} - 9 \\ s(u(2)) = 144 - 9 \\ \\ s(u(2)) = 135](https://tex.z-dn.net/?f=u%28t%29%20%3D%207t%20-%202%20%5C%5C%20u%282%29%20%3D%207%282%29%20-%202%20%5C%5C%20u%282%29%20%3D%2014%20-%202%20%5C%5C%20u%282%29%20%3D%2012%20%5C%5C%20%20%5C%5C%20s%28t%29%20%3D%20%20%7Bt%7D%5E%7B2%7D%20-%209%20%5C%5C%20%20s%28u%282%29%29%20%3D%20%20%7B%2812%29%7D%5E%7B2%7D%20%20-%209%20%5C%5C%20s%28u%282%29%29%20%3D%20144%20-%209%20%5C%5C%20%20%5C%5C%20s%28u%282%29%29%20%3D%20135)
I hope I helped you^_^
The midpoint lines are half the opposite side length.
Line DE is given as 7 , So Line F = 7 x 2 = 14
Line EF is given as 12, so Line D = 12 x 2 = 24
Line DF is given as 16, so line E = 16 x 2 = 32
The perimeter is the sum of the 3 sides:
Perimeter = 14 + 24 + 32 = 70
