Answer:
57. You Take 180 And Subtract It From The 65 And 58 To Get Your Answer
Step-by-step explanation:
40 flights if you're asking how many flights happen in 1 hour.
Let the width be x.
Width = x
Length = 4x + 7
The area is 650 m²
x(4x + 7) = 650
4x² + 7x - 650 = 0
Using quadratic formula:

a = 4, b = 7, c = -650


Width = 11.9m
Length = 4(11.9) + 7 = 54.6m
Answer: Length = 54.6m and width = 11.9m
