The Roman Coliseum Is an Elliptical Amphitheater Measuring Approximately 188 $\frac { x ^ { 2 } } { a ^ { 2 } } + \frac { y ^ { 2 } } { b ^ { 2 } } = 1$

The Roman Coliseum is an elliptical amphitheater measuring approximately 188 meters long and 156 meters wide.Find an equation to model the coliseum that is of the form $\frac { x ^ { 2 } } { a ^ { 2 } } + \frac { y ^ { 2 } } { b ^ { 2 } } = 1$ .

A) $\frac { x ^ { 2 } } { 6084 } - \frac { y ^ { 2 } } { 8836 } = 1$
B) $\frac { x ^ { 2 } } { 8836 } + \frac { y ^ { 2 } } { 6084 } = 1$
C) $\frac { x ^ { 2 } } { 8836 } + \frac { y ^ { 2 } } { 6084 } = 0$
D) $\frac { x ^ { 2 } } { 188 ^ { 2 } } + \frac { y ^ { 2 } } { 156 ^ { 2 } } = 1$
E) $\frac { x ^ { 2 } } { 6084 } + \frac { y ^ { 2 } } { 8836 } = 0$
