Answer: 32 sides
Step-by-step explanation:
Formula for interior angle of a polygon = ( n - 2 )180°, where n is the number of sides of the polygon
Now equate the formula to 5400°
( n - 2 ) × 180° = 5400°
open bracket by multiply by 180°
180n° - 360° = 5400°
180n° = 5400° + 360°
180n° = 5760
n = ⁵⁷⁶⁰/₁₈₀
n = 32
so the polygon has 32 sides

Step-by-step explanation:
The perimeter is the length of all the sides in the figure.
The arc of the semi- circle is included in this.
length of arc =
πd ← d is the diameter
here d = 8, hence
arc =
π × 8 = 4π ← exact length
Perimeter = 10 + 8 + 10 + 4π ≈ 40.57 in ( nearest hundredth )
2x+10, multiply to two each term x and 5
