Step-by-step explanation:
PC=QC=RC
3x+7=51-x
3x+x=51-7
4 x=44
x=11
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
