Find the area of the shaded figure

At a gynecologists convention Dr. Goldfinger began to read his paper on "The Variation of the Clitoris".

"One of the most unusual cases I ever came across," he told his audience, "was a clitoris that had a close resemblance to a watermelon."

Dr. Goldfinger was interrupted by another doctor, who said that he might have been examining an enlarged organ but to compare it to a watermelon would indeed be frivolous.

Goldfinger stared him down and replied: "I wasn't referring to size but to taste."
