Explanation:

Step1: Identify side - lengths

The side - lengths of the figure are 3 in, 4 in, 5 in, 3 in, 8 in, 7 in.

Step2: Calculate perimeter

Perimeter is the sum of all side - lengths. So, $P=3 + 4+5 + 3+8 + 7$.
$P=(3 + 4)+5+(3 + 8)+7$
$P = 7+5 + 11+7$
$P=(7 + 5)+11+7$
$P = 12+11+7$
$P=(12 + 11)+7$
$P = 23+7$
$P = 30$

Answer:

30
