Question

what is the perimeter of this pentagon? 4 cm 4 cm 4 cm 4 cm 4 cm p =? cm

Explanation:

Step1: Recall the formula for perimeter

The perimeter \(P\) of a polygon is the sum of the lengths of its sides. For a regular pentagon (a pentagon with all sides equal), \(P = 5\times\) side - length.

Step2: Substitute the side - length

Given that the side - length \(s = 4\) cm. Using the formula \(P=5s\), we substitute \(s = 4\) into the formula: \(P = 5\times4\).

Step3: Calculate the result

\(5\times4=20\).

Answer:

\(20\)
