Answer:
length of arc of sector is 15 .8 m
Step-by-step explanation:
Radius of the sector r = 5.7 m
Perimeter of the sector P = 27.2 m
Perimeter of the sector is
27.2= Radius + length of arc+ radius
27.2= 2*Radius + arc length of sector
27.2= 2* 5.7+ arc length of sector
arc length of sector= 27.2-11.4
arc length of sector = 15.8 m
Hence, the Area of sector= 45.03 cm².
