∫△ABE is an equilateral triangle with a side length of 2,

What is the height and side length of Be? 12=3,

∴a(2,2+3)；

(2) As shown in the figure,

Pentagon a1b1c1d1e1is the desired figure;

(3)∫△ABE is an equilateral triangle with a side length of 2.

∴S△ABE=34×22=3, and the area of rectangular BCDE is 1×2=2.

The area of pentagonal ABCDE is 2+3,

∵ pentagonal ABCDE is similar to pentagonal A1b1c1d1e1,and the similarity ratio is 1: 3.

Then the area of Pentagon A1b1c1d1e1is 9(2+3)= 18+9. What's your comment on this answer?
