If the area of the following rectangular abcd is 100, and e is the midpoint of ab, what is the area of the shaded part?

the shape is shown in the attachment (sorry for it being so messy)

A, b, c, and d have the coordinates (-8, 1), (-2, 4), (-3, -1), and (-6, 5), respectively. which sentence about the points is true? a. a, b, c, and d lie on the same line. b. and are perpendicular lines. c. and are parallel lines. d. and are intersecting lines but are not perpendicular. e. and are parallel lines.

Prove that quadrilateral is a rhombus.

In the triangles, bc =de and ac fe.if the mzc is greater than the mze, then ab isdfelth
