Answer:
perimeter of figure is perimeter of arc +perimeter of the two segments
perimeter of arc is πr
22/7×2.8/2=4.4cm
length of two segments = 4 cm
perimeter of figure is 4.4cm+ 4 cm=8.4 cm
Answer:
8.4 cm
Step-by-step explanation:
total parimeter= parimeter of semicircle + 2cm + 2cm
diameter of semi circle(d)= 2.8cm
radius " " " (r) = 2.8/2= 1.4cm
total parimeter= (2πr/2)+2cm+2cm
=(πr)+4cm
=(22/7*1.4)+4cm
=(22*0.2)+4cm
=4.4+4cm
=8.4cm
