P = 2(l + w)
p/2 = l + w divide both sides by 2
p/2 - w = l subtract both sides by w
l = (p - w)/2
so c, is your answer.

Answer:
answer is 24.56cm
perimeter of half/semi circle =
r + 2r
<em>one semi circle semi circles perimeter: </em>
<em>*2+2*2 =10.283cm, </em>
<em>for two semi circles= 2*10.283 =20.566cm</em>
without the line below for two semi circle: 20.566-4-4=12.566 cm
both da side of rectangle is 6cm+6cm=12cm
now add the 12.566+12=24.56cm
The answer is true
Hope this helped!
