Answer:
15 degrees
Step-by-step explanation:
angle a= (180-90)/2=90/2=45 degrees
angle QRP = 60
Angle b = 60-45=15 degrees
Length of outer boundary =30m
So area of outer boundary =30×30
= 900m²
Length of inner boundary of path=30-1= 29m
Inner area =29×29 =841m²
So area of path is= outer area - inner area
=900- 841
= 59m²
