whats the perimeter of a rhombus of height of 4.55 and a base of 5.2

 

without mistake:

\(\begin{array}{|rcll|} \hline a^2 &=& \left(\dfrac{5.2}{2}\right)^2 +\left(\dfrac{4.55}{2}\right)^2 \\ a &= & \sqrt{2.6^2+2.275^2} \\ &= & \sqrt{6.76+5.175625} \\ &= & \sqrt{11.935625} \\ &= & 3.45479738914 \\\\ \text{Perimeter} &=& 4\cdot a \\ &=& 4\cdot 3.45479738914 \\ &=& 13.8191895566 \\ \hline \end{array}\)
