Answer:

a: 2 cm; b: 34 cm; c: 46 cm^2

Explanation:

the missing side length is 2

9 - (4 + 3) = 2

when you add them all together you get

5 + 4 + 2 + 2 + 3 + 3 + 6 + 9 = 34

the perimeter is 34

you can split the shape up in multiple ways

you can split it into three rectangles

(5 * 4) + (2 * 4) + (3 * 6)

20 + 8 + 18 = 46
