Answer:
84 mm Sq.
Explanation:
first do the square you see, 6 × 6 which is 36. then do one of the squares and the area is 8 × 6 which is 48 then divide that by 2. you will use the same equation for the other triangle, and the area for it should be the same. last add all of those together so 36 + 24 + 24 = 84 mm sq.
