Final answer:
The perimeter of abcdef is 33m
Step-by-step explanation:
To find the perimeter of abcdef, we need to find the lengths of all the six sides of the figure.
Since abcd is a kite, the length of ab is equal to the length of dc, which is 7m.
Since adef is a rhombus, all four sides are equal in length. Since bc is 4m, the length of de is also 4m.
Therefore, the perimeter of abcdef is 7m + 4m + 7m + 4m + 7m + 4m = 33m.
