Area of rectangle = 
Expand the expression
(distributive property of multiplication)

Combine like terms

Expression for the area of the rectangle = 
JK = MN because of Given
∠JLK = ∠MLN because of the vertical angle theorem
JL = LN because of definition of midpoint
ΔJLK = MLN because of SAS
∠K = ∠N because corresponding angles of congruent triangles are congruent.
