I split A into 3 parts. A1 is a semicircle with r=3, so the area is half of pi x 9, which is roughly 14.1. A2 and A3 together make a square 6x6=36, so the area of A is 50.1cm², I think.

For the perimeter of B, the 3 green arcs are ¾ of a circle r=6, so ¾ x pi x 12=28.3. The pink arc is pi x 3 = 9.4 and the yellow line is 6cm. The total should be 43.7cm. I rounded as I went along, so I might not have it exactly right.
