.
The side  JK  is horizontal y = 4. Its length is -1 - (-6) = 5 units.


The side  LM is horizontal y = -4. Its length is -1 - (-6) = 5 units.


The side  JL  is vertical y = x= -6.  Its length is 4 - (-4) = 8 units.


The side  KM  is vertical y = x= -1.  Its length is 4 - (-4) = 8 units.


The quadrilateral  JKML  (! in this order !)  is a rectangle with dimensions 5 and 8 units.


Its area is 5*8 = 40 square units.
