Welcome to AskIITians
The given equation is (x^2/49) + (y^2/36) = 1
It can be written as (x^2/7^2) + (y^2/6^2) = 1
It is noticed that the denominator of x^2/49 is greater than the denominator of the y^2/36
On comparing the equation with (x^2/a^2) + (y^2/b^2) = 1, we will get
a= 7 and b = 6
Therefore, c = √(a^2– b^2)
Now, substitute the value of a and b
⇒ √(a^2– b^2) = √(72– 62) = √(49-36)
⇒ √13
Hence, the foci coordinates are ( ± √13, 0)
Eccentricity, e = c/a = √13/ 7
Length of the major axis = 2a = 2(7) = 14
Length of the minor axis = 2b = 2(6) =12
The coordinates of the vertices are ( ± 7, 0)
Latus rectum Length= 2b^2/a = 2(6)^2/7 = 2(36)/7 = 72/7
