Sorry if it is a silly question. I want to find an inner quadrilateral area for that I need one of the inner quadrilateral lengths. I don't know the formula if you can please help me.
Lengths of the quadrilateral(irregular rectangle) are as follows:
A > 43.8 B > 38.4 C > 243.0 D > 244.6
Now I want to know the length of the question mark I mentioned here. Because I have inner quadrilateral with new lengths as below,
a > ??????????(I want to find) b> 38.4 c > 80 d > 80
please help me thanks.
