1. Problem Description

The problem asks us to find the perimeter of kite ABCDABCD. We are given that AE=EC=8AE = EC = 8, BE=4BE = 4, and DE=16DE = 16. We have already found that CD=85CD = 8\sqrt{5}.

2. Solution Steps

The perimeter of kite ABCDABCD is AB+BC+CD+DAAB + BC + CD + DA. Since AB=BCAB = BC and AD=CDAD = CD, the perimeter is 2(AB+CD)2(AB + CD).
First, we need to find ABAB. In right triangle ABEABE, we have AE=8AE = 8 and BE=4BE = 4.
By the Pythagorean theorem, AB2=AE2+BE2AB^2 = AE^2 + BE^2.
AB2=82+42=64+16=80AB^2 = 8^2 + 4^2 = 64 + 16 = 80.
AB=80=165=45AB = \sqrt{80} = \sqrt{16 \cdot 5} = 4\sqrt{5}.
Next, we already know CD=85CD = 8\sqrt{5}.
The perimeter is 2(AB+CD)=2(45+85)=2(125)=2452(AB + CD) = 2(4\sqrt{5} + 8\sqrt{5}) = 2(12\sqrt{5}) = 24\sqrt{5}.

3. Final Answer

24524\sqrt{5}
