=>308=π r²/2

=>308*2/22/7=r²

=>r²=196

=>r=14

we know that,

perimeter of semicircle=π r+2r

=22/7*14+2*r

=44+28

= 72m.

hope this helps you.........pls mark as best

**to find out the area of semi circular path = r² /2 = 308**

**r² = 616/**

**∴ r = 14 cm**

perimeter = r + 2r

= 22/7*14+2*r

= 44+28

= 72 cm.

∴ the perimeter = 72 cm.
