Question

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

Explanation:

Step1: Count side - lengths

Count the number of each type of side - length in the figure. There are 2 sides of length $d$, 2 sides of length $e$, and 8 sides of length $f$.

Step2: Write perimeter formula

The perimeter $P$ of a polygon is the sum of the lengths of its sides. So, $P = 2d+2e + 8f$.

Answer:

$2d + 2e+8f$
