Solve the Problem B) C) D)

Solve the problem.
-A rectangle has its center at the origin. It has two sides of length 4 a which are parallel to the horizontal axis and two sides of length 2 a parallel to the vertical axis. Find polar coordinates of the vertices.

A) $\approx \left( 2 a \sqrt { 5 } , 63.4 ^ { \circ } \right) , \left( 2 a \sqrt { 5 } , 116.6 ^ { \circ } \right) , \left( 2 a \sqrt { 5 } , 243.4 ^ { \circ } \right) , \left( 2 a \sqrt { 5 } , 296.6 ^ { \circ } \right)$
B) $\approx \left( a \sqrt { 5 } , 30 ^ { \circ } \right) , \left( a \sqrt { 5 } , 150 ^ { \circ } \right) , \left( a \sqrt { 5 } , 210 ^ { \circ } \right) , \left( a \sqrt { 5 } , 330 ^ { \circ } \right)$
C) $\approx \left( a \sqrt { 5 } , 26.6 ^ { \circ } \right) , \left( a \sqrt { 5 } , 153.4 ^ { \circ } \right) , \left( a \sqrt { 5 } , 206.6 ^ { \circ } \right) , \left( a \sqrt { 5 } , 333.4 ^ { \circ } \right)$
D) $\approx \left( 2 \mathrm { a } \sqrt { 5 } , 26.6 ^ { \circ } \right) , \left( 2 \mathrm { a } \sqrt { 5 } , 153.4 ^ { \circ } \right) , \left( 2 \mathrm { a } \sqrt { 5 } , 206.6 ^ { \circ } \right) , \left( 2 \mathrm { a } \sqrt { 5 } , 333.4 ^ { \circ } \right)$
