Explanation:

Step1: Recall the formula for perimeter

The perimeter \(P\) of a polygon is the sum of the lengths of its sides. For a trapezoid with side lengths \(a\), \(b\), \(c\), and \(d\), \(P=a + b + c + d\).

Step2: Substitute the given values

Here, \(a = 6\) cm, \(b = 8\) cm, \(c = 9\) cm, and \(d = 11\) cm. So \(P=6+8 + 9+11\).

Step3: Perform the addition

First, \(6+8=14\), then \(14 + 9=23\), and finally \(23+11 = 34\).

Answer:

\(34\) cm
