A = length x width
15,000 = (w + 30) x w
15,000 =

+ 30w
0 =

+ 30w - 15,000
Use quadratic formula to find that w= -15 + or - 5

. Because distance cannot be negative, the width is -15 + 5

meters or approximately 108.39 meters. This means that the length is approximately 138.39 meters.
Answer:
75.062c
Step-by-step explanation:
To find the missing side use pythagorean theorem
So 
Solve for b, b= 6.021
To find the area use
bh
So
(6.021+19)(6)= area
And you get 75.062
ADC should measure to 115 degrees if both measurements are equal to 180 degrees.
If not, ADC might be 25 degrees if both measurements are equal to 90 degrees.
Hope this helps.
