Find the perimeter of the parallelogram with these vertices. (1,5), (-6,5), (6.-3), (-1,-3).

Answer 1

Opposite sides of a parallelogram are equal, so you just need to find the lengths of two consecutive sides and double that to get the perimeter.

Between (1,5) and (-6,5) is a straight line so the length of the side should be obvious.

Between (-6,5) and (-1,3) you can use the distance formula to find the length.
