Heya!!!
Equation of ellipse in standered form is
x²/a² + y²/b² = 1
Where a is length of semi major axis and b is length of semi minor axis.
e = c/a = 2/3
Where c = √(a² - b² )
( a² - b² ) = 4a²/9
b² = 5a²/9.... ( ii )
And
length of latus rectum is = 2b²/a
2b²/a = 5
b² = 5a/2 .... ( i )
4rm ist and second we get
5a²/9 = 5a/2
a = 9/2
a² = 81/4 And b² = 45/4
So, Equation of ellipse is
4x²/81 + 4y²/45 = 1
45x² + 81y² = ( 45 × 81 )/4
9 ( 5x² + 9y² ) = ( 45 ×81)/4
4( 5x² + 9y² ) = ( 45 × 81)/9
20x² + 36y² = 45×9
20x² + 36y² = 405

oh' yar..
how silly we both are
xD xD
mine ans was absolutely right.. only simplification remains left.
