.04 Im pretty sure this is the answer
Answer: The measure of each exterior angle is 6.4°.
Step-by-step explanation:
Since we have given that
Number of sides = 56
We have to find the measure of each exterior angles:
As we know the formula :

Hence, the measure of each exterior angle is 6.4°.
A = lw
A = 5.45 × 3.275
A = 17.84875
The area of the frame (without rounding) is 17.84875.
