Lamar is writing a coordinate proof to show that a segment from the midpoint of the hypotenuse of a right triangle to the opposite vertex forms two triangles with equal areas. He starts by assigning coordinates as given.
To find the area of △MNL, the length of the base, segment ML is _____, and the height is ______. So an expression for the area of △MNL is ab.

• ab,b
• b, 2a
• 2a, b
• 4b, a
