Question

find the perimeter of the figure below, in inches.
14.1 in
10.2 in
10.2 in
24.3 in
8.9 in
34.5 in
19.1 in
10.2 in
14.1 in
(note: diagram is not to scale)
answer
p = 156.2

Explanation:

Step1: Sum up all the horizontal lengths

$$10.2+14.1 + 24.3+14.1+34.5+10.2=107.4$$

Step2: Sum up all the vertical lengths

$$8.9+10.2+10.2+19.1+10.2=58.6$$

Step3: Calculate the perimeter

Perimeter \(P=(sum\ of\ horizontal\ lengths + sum\ of\ vertical\ lengths)\times2\)
$$P=(107.4 + 58.6)\times2=166\times2 = 166$$

Answer:

\(166\)
