Double facts the even and odd numbers for example 2×2=4
(350x2=700) + (125x2=250) 700+250=950 so the perimeter is 950 meters long I hope this helps!

Answer:
78.5 km
Step-by-step explanation:
Measured at the airport, the angle between the two planes is ...
180° -60° -50° = 70°
The law of cosines tells us the distance between the planes is ...
d = √(50² +80² -2·50·80·cos(70°)) ≈ √6163.84 ≈ 78.5 . . . km
The planes are about 78.5 km apart.
i believe the answer would than have to be 17,24,31,45,52
