Is there more information?
As stated, there is no unique solution.
i've been trying to calculate the perimeter of a parallelogram
by only knowing the length of the diagonals (which are 7 and 9 units).Code:S R * - - - - - - - - * / * * / / * O * / / * / b / 4½ * θ * 3½ / / * * / * - - - - - - - - * P a Q
We have parallelogram with diagonals
. . intersecting at
Law of Cosines: .
. . Hence: .
It can be shown that: .
Hence, the perimeter, , is a function of , not a constant.
