#### Answer:

4299.322531

#### Explanation:

lets draw a perpendicular line on **B** .

suppose, the length of the perpendicular is **D**

now, the problem says, the angle between **A** and **B** is

now,

in,

now, by putting the values, **B=48** and **tan #(5pi)/12#** ,

so,

The area of

now, by putting the value of

**B**and

**D**in the above equation, we get,
