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 each
If the sides are 11 and 8, the area will be 11 × 8.
11 × 8 = 88
Thus, the area is .
Check:
11 + 11 + 8 + 8 = 22 + 16 = 38.
So we are correct.
Hope this helps!

Based on the dimensions of the regular pentagon, the approximate area can be found to be 342 cm².
<h3>How to solve for approximate area?</h3>The area of the pentagon can be found by the formula:
= 5 x 1/2 x Length of pentagon x apothem of pentagon
The apothem is:
= √(12² - (14.1/2)²)
= 9.7
The approximate area of the pentagon is therefore:
= 5 x 1/2 x 14.1 x 9.7
= 342 cm²
