The value of is    

Step-by-step explanation:

Given,

Parallelogram ,,altitude corresponding to and is and

From figure,

Area of Parallelogram ,

When as base and as height,

Area of Parallelogram

                                                 

                                             

When as base and as height,

Area of Parallelogram

                                                   

Area of Parallelogram are equal on both sides,

So,

⇒

∴ (∵ )

So, The value of is
