A rectangle or a parallelogram
A rectangle.
0.3
The squared area of a triangle is half of its base times its perpendicular height. Or as: 0.5*base*perpendicular height = area of a triangle
All sides of all of them are the same length and are parallel to each other.
The best classification for a parallelogram that has perpendicular diagonals is a rhombus. A rhombus has four sides that are congruent. The also diagonals bisect the vertex angles of this type of parallelogram.

my best answer is parallelogram if you dis agree please respond
On the list of choices that you posted along with your question, there's no phrase that defines a parallelogram well at all.
A seven sided figure has 14 diagonals. Each vertices has 4 diagonals (but of course some are shared diagonals). The best thing to do is draw a regular heptagon, draw all the diagonals (lines connecting non-adjacent vertices) in pencil and then go back with a red or blue pen and count the diagonals as you trace each line in the different color.
