24 m

Step-by-step explanation:

Add the complete outside of the shape. One side measure is 5 m. The other measure is 7 m. Add 5 + 7 to get 12 m. This is your answer for half of the shape. Double it to find the other completely symmetrical half. To double it, use the equation 12 x 2 = 24.

Hope it helps and is correct!
