Question

perimeter = 45 in. what is the length of each side? regular pentagon ? in use a

Explanation:

Step1: Recall perimeter of regular pentagon

A regular pentagon has 5 equal sides. Perimeter \( P = 5 \times \text{side length} \) (let side length be \( s \)), so \( P = 5s \).

Step2: Solve for side length

Given \( P = 45 \) in, substitute into formula: \( 45 = 5s \). Divide both sides by 5: \( s=\frac{45}{5}=9 \).

Answer:

9 inches
