The answer is correct!!!

In order to solve this problem, you need to know basic trigonometry. I don't see any other method to solve this 'cookie'.

 

BD = CD = 4            BI = 5        DI = 4

 

In order to find the length of AD, you have to find angle B and multiply its tangent by 4.

 

[ABC] = BD * AD
