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? 22 ft. 30 ft. 12 ft. 24 ft.

Explanation:

Step1: Recall the formula for the perimeter of a trapezoid

The perimeter \(P\) of a trapezoid is \(P=a + b+ c + d\), where \(a,b,c,d\) are the lengths of its sides.

Step2: Identify the side lengths

Here, \(a = 3\) ft, \(b = 5\) ft, \(c = 9\) ft, \(d = 4\) ft.

Step3: Calculate the perimeter

\(P=3 + 5+9 + 4\)
\(P=(3 + 5)+(9 + 4)\)
\(P = 8+13\)
\(P = 22\) ft

Answer:

22 ft.
