A helicopter landing pad has a length of 80 ft and a width of 50 ft. A safety zone of uniform width, which is not to be entered during landing, surrounds the landing pad. The landing pad and safety zone together have a combined area of 10800 ft2, what is the uniform width (safety zone) around the landing pad?
Step-by-step explanation:
Let w be the uniform width of the safety zone.
We have combined area = 10,800ft².
=> Combined area = Length * Width
= (80 + 2w)(50 + 2w)ft².
Therefore (80 + 2w)(50 + 2w) = 10,800.
=> 4,000 + 260w + 4w² = 10,800
=> 4w² + 260w - 6,800 = 0
=> w² + 65w - 1,700 = 0
=> (w - 20)(w + 85) = 0
=> w = 20 or w = -85
(w = -85 is rejected as width must be positive)
Hence the uniform width is 20ft.
What is the area??? I don't understand I have tried so hard.

s=2πcx+3πc^2 solve for x
Answer:
x = (s - 3πc^2) / 2πc.
Step-by-step explanation:
s = 2πcx + 3πc^2
2πcx = s - 3πc^2
x = (s - 3πc^2) / 2πc.

Answer:
1. Given
2. Corresponding Angles Theorem
3. ∠NPO ≅ ∠MQN (or something similar)
4. AA Similarity Theorem
Step-by-step explanation:
1. Line MQ || Line OP is the given statement.
2. ∠QNM on the left triangle corresponds to ∠PNO on the second triangle.
3. These two angles are cut by a transversal (Line MP), and thus are congruent.
4. ∠MQN and ∠NMQ are congruent to ∠NOP and ∠NPO respectively, so the triangles are similar.
