Area of semi circle = π r² /2
⇒π r² /2 = 308
⇒ r² =616/π
        =196
so, radius, r = 14 cm
now perimeter = 2π r/2 = π r
                        =π ×14
                        = 44 cm
∴perimeter = 44 cm

i am ofcourse cool
good then :)

area of semi circle=π r²/2
=>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
