P = 2(L + W)
P = 22
L = 2W + 2
22 = 2(2W + 2 + W)
22 = 2(3W + 2)
22 = 6W + 4
22 - 4 = 6W
18 = 6W
18/6 = W
3 = W.....this is the width
L = 2W + 2
L = 2(3) + 2
L = 6 + 2
L = 8 meters <=== this is the length

Step-by-step explanation:
Answer:2 4 and 5
Step-by-step explanation:
Let x be the distance between the plane and the airport.
We have,
Angle of depression = 22°
Altitude = 1800 m
Sin 22° = Opposite/Hypotenuse
=> Sin 22° = Altitude/x
=> Sin 22° = 1800/x
=> x × Sin 22° = 1800
=> x = 1800/Sin 22°
=> x = 1800/0.3746065934
=> x = 4805.04089 m
