Solve the problem.
-A rectangle has its center at the origin. It has two sides of length a which are parallel to the horizontal axis and two sides of length 5 a parallel to the vertical axis. Find polar coordinates of the vertices.
A)

\approx \left( a \sqrt { 26 } , 11.3 ^ { \circ } \right) , \left( a \sqrt { 26 } , 168.7 ^ { \circ } \right) , \left( a \sqrt { 26 } , 191.3 ^ { \circ } \right) , \left( a \sqrt { 26 } , 348.7 ^ { \circ } \right)

\approx \left( \frac { a \sqrt { 26 } } { 2 } , 78.7 ^ { \circ } \right) , \left( \frac { a \sqrt { 26 } } { 2 } , 101.3 ^ { \circ } \right) , \left( \frac { a \sqrt { 26 } } { 2 } , 258.7 ^ { \circ } \right) , \left( \frac { a \sqrt { 26 } } { 2 } , 281.3 ^ { \circ } \right)
