I need help with # 6

Answer:
8 on the left and right sides, 15 on the top and bottom.
Step-by-step explanation:
If 8 is on one side, it is also on the other side.
38 - 8 = 30
30 ÷ 2 = 15
Answer:
11 and 88
Step-by-step explanation:
If one side measures 8, that means that another one does.
8 + 8 = 16
38 = 16 + 2n
Subtract 16:
22 = 2n
11 = n
So the missing sides are [tex]\boxed{11}[/tex] each
If the sides are 11 and 8, the area will be 11 × 8.
11 × 8 = 88
Thus, the area is [tex]\boxed{88}[/tex].
Check:
11 + 11 + 8 + 8 = 22 + 16 = 38.
So we are correct.
Hope this helps!
