Answer:
[tex]\displaystyle 40\:mm.^2 = A \\ 32\:mm. = P[/tex]
Step-by-step explanation:
All vertices meet at right angles, so sealing off these two rectangles will give you this:
[tex]\displaystyle [2][4] + [4][8] = 8 + 32 = 40; 40mm.^2 \\ 4 + 6 + 2 + 4 + 8 + 8 = 32; 32mm.[/tex]
* The missing sides are 4 and 6.
