P = 2L +2w = 58 ----> L+w = 29 ----> L = 29-w
A = L*w = 204
Now substitute "29-w" for L in Area equation:
(29-w)w = 204
This gives a quadratic
w^2 - 29w + 204 = 0
Use quadratic formula:
w = 12, w = 17
Either value will work since L=29-w, the other number becomes length.
Therefore the final dimensions of the rectangle are 12 by 17.

Answer:
108°
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
2a is an exterior angle, thus
2a = a + 10 + 44 = a + 54 ( subtract a from both sides )
a = 54
Thus 2a = 2 × 54 = 108° ← exterior angle
