Answer:
Ellipse perimeter = PI*(3*(a+b) -sqrt (10*a*b + 3*(a^2 + b^2)) (See Attached)
where a = semi-major axis and b = semi-minor axis
a = 15/2 = 7.5 and b = 7.5/2 = 3.75
Ellipse perimeter = PI * (3 * (7.5 + 3.75) - sqrt( 10 * 7.5 * 3.75) + 3 * (7.5^2 + 3.75^2)
Ellipse perimeter = PI * (33.75 - sqrt[( 281.25 + 3* (56.25 + 14.0625
)]
Ellipse perimeter = PI * (33.75 - sqrt(281.25 + 210.9375
)
Ellipse perimeter = PI * (33.75 - sqrt (492.1875
)
Ellipse perimeter = PI * (33.75 -22.1852991866
)
Ellipse perimeter = PI * 11.5647008134
Ellipse perimeter = 3.1415926536 * 11.5647008134
Ellipse perimeter = 36.3315791163
or Ellipse perimeter = 36.33 feet (rounded)
