a parallelogram has the vertices (1,2), (4,4), (2,1), and (3,3). determine what type of parallelogram. find the perimeter and area. i found the parallelogram part and its a rhombus but i cant find the perimeter and area

You must have found the length of each side to determine it was a rhomus
I found each side to be √29
so just take 4√29 for the perimeter.
the area of a rhomus = (1/2)product of their diagonals
so just find the length of the diagonals and go from there.
