Answer:
a = 33
Step-by-step explanation:
IN a parallelogram consecutive angles are supplementary, thus
5a - 52 + 5a - 98 = 180, that is
10a - 150 = 180 ( add 150 to both sides )
10a = 330 ( divide both sides by 10 )
It's a parallelogram so the each side is a transverse across two opposite parallel sides, so make the usual congruent and supplementary angles.
Here we have T and U must be supplementary angles because they're consecutive interior, if I remember the term.
T + U = 180°
5a - 98° + 5a - 52° = 180°
10a = 180° + 98° + 52° = 330°
a = 33°
Answer: 33°

easy way...
multiply Base x height (for both)
30 inches x 12 inches = 360 in
16 in. x 12 in = 192 in.
then add both
360 + 192 = 552
A=552 in²
