Answer:
The length of the other diagonal is 10 units
Step-by-step explanation:
we know that
The area of a Rhombus is equal to
[tex]A=\frac{1}{2}[D1D2][/tex]
where
D1 and D2 are the diagonals of the rhombus
we have
[tex]A=65\ units^{2}[/tex]
[tex]D1=13\ units[/tex]
substitute in the formula and solve for D2
[tex]65=\frac{1}{2}[(13)D2][/tex]
[tex]130=[(13)D2][/tex]
[tex]D2=130/13=10\ units[/tex]
