Question

once youve covered the panel with fabric, youll outline the shape with a strip of led lights. what length of led strip do you need to surround the panel?

Explanation:

Step1: Identify the lengths of sides.

The trapezoid has side - lengths 3 ft, 5 ft, 9 ft, and 5 ft.

Step2: Calculate the perimeter.

The perimeter \(P\) of a polygon is the sum of its side - lengths. So \(P=3 + 5+9 + 5\).
\(P=(3 + 9)+(5 + 5)=12 + 10=22\) ft.

Answer:

22 ft
