Answer:
P=23.4
Step-by-step explanation:
so using the pytogoren theroum
c2-b2= a2
so a= 6.9
so P= 6.9+6.8+9.7=23.4
if my answer helped please mark as brainliest.
Answer: 
Step-by-step explanation:
General equation of ellipse :
Given: Vertices of ellipse : (± 9,0)
Since the vertices are of the form (± a, 0).
i.e. a=9
Thus, the major axis is along x-axis.
Also, foci of the ellipse = (±5,0)
Since, foci is of the form (± c,0), i.e. c=5
Since

Equation of ellipse :

Hence, the required equation : 
C but it also depends on hte type of job
