The correct options are
A eccentricity is 5√3
B Length of major axis is 5√2
C Length of latus rectum is 10√29
D Center is (1,3)
x−y+2=0 and x+y−4=0 are perpendicular lines
Let
x−y+2√2=X and x+y−4√2=Y
4(√2X)2+9(√2Y)2=25
⇒X2258+Y22518=1
a2=258, b2=2518
Center of ellipse is the point of intersection of x−y+2=0 and x+y−4=0 that is (1,3)
e2=1−b2a2 (as a>b)
=1−818=1018=59
e=√53
Length of major axis is 2a=2×52√2=5√2
Length of latus rectum
=2b2a=2×2518×2√25=10√29
