How do you find the area of a rhombus using its perimeter?

You need more information.

Area # = (p^2 sin theta)/16#

where #p# is the length of the perimeter and #theta# is one of the internal angles of the rhombus.

Explanation:

If the perimeter is of length #p# then the area is anywhere in the range #0# to #(p/4)^2 = p^2/16#
If the perimeter is of length #p# then the length of one side is #p/4#.

If we place one side of the rhombus horizontally, then the area is equal to the product of the base and height, The base is of length #p/4# and the height is #p/4 sin theta#, where #theta# is an internal angle of the rhombus.
