講真我覺得呢條題目絕對有出現係香港各大past paper或者練習入面 一個好standard嘅trick黎 基本上淨係要搵個area of sector - area of triangle
英國人睇黎都係太幸福無操過卷

畫個等邊三角形入去已經計完啦有幾難丫

真係要就let point D E be intersection points of circles with centre A and B
area bounded by minor arc DE of circle A and that of circle B
或者係樓主個方法就area of sector ABD - area of triangle ABD 之類
都係英文或者中文文字問題
言之成理就得啦
