If ABCD is a parallelogram, what is the value of x?35
15 units
Anything you like (as long as it is > -16 so that BC > 0). In a parallelogram, adjacent sides do not impose any restrictions on one another.
It is 16 units.

Assuming ABCD marks the four corners, the perimeter = sum of the four sides = (AB + BC + CD + DA) where AB == the side from A to B etc.

In parallelogram ABCD, AC=BD. Is ABCD a rectangle?
A+=14 * * * * * Not sure what the above answer means. But whatever it is, it is not the correct answer to this question! ae is half of ad so the second figure has the linear dimensions of the second are half that of the first. Therefore, the perimeter is half ie 27 units.
none of these are correct
It is possible, but it all depends on what they are lengths of!
160 degrees.
25 units
