Question

calculate the eccentricity of this ellipse using the equation d/l = e; where d=24 and l=48.

Explanation:

Step1: Substitute values into formula

$e=\frac{d}{l}$, substituting $d = 24$ and $l=48$ gives $e=\frac{24}{48}$.

Step2: Simplify the fraction

$\frac{24}{48}=\frac{1}{2}=0.5$

Answer:

$0.5$
