The perimeter of a rectangle is calculated as
Perimeter= 2(length + breadth )
So, Perimeter = 2*length + 2*breadth
Now we are given the length as 34.2 meters and breadth as 27.8 meters
So the perimeter will be
2(34.2+27.8) meters
which equals 2(62) meters
Hence Perimeter = 124 meters

Answer:
C) 14 cm
Step-by-step explanation:
A triangle solver can quickly show you the third side is 14 cm.
__
The law of cosines can be used for this purpose. If the given sides are 'a' and 'b', and the third side is 'c', then that law tells you ...
c² = a² +b² -2ab·cos(C)
c² = 7² +11² -2·7·11·cos(100°) ≈ 196.74
c ≈ √196.74 ≈ 14.03
The length of the third side is about 14 cm.
