Help with the area please

i think its 58 or 70 sorry if i am wrong
Step-by-step explanation:
Answer:
Area = 58 cm²
Step-by-step explanation:
8 x 5 = 40
6 x 3 = 18
We don’t know the side length of the middle shape. It must be two lines because opposite sides can’t have different lengths, and they do.
So we can just add what we know.
40 + 18 = 58
