Question

write an expression that represents the perimeter of the figure below. write your answer in simplified form.

Explanation:

Step1: Recall perimeter concept

Perimeter is sum of all side - lengths.

Step2: Add all side - lengths

$P = l + m + m + p + n + l + m + r+q + m$

Step3: Combine like - terms

$P=(l + l)+(m + m + m + m)+p + n + r+q$
$P = 2l+4m + p + n + r+q$

Answer:

$2l + 4m + p + n + r+q$
