Question

Which of the following traffic signs has a perimeter of 18 ft?

• A.
• B.
• C.
• D.

Answer 1

The correct option is D

We have to identify traffic sign that has a perimeter of 18 ft.

We know that the perimeter of any polygon is the sum of the length of all the sides.

Let's find the perimeter of all the given traffic signs.


$\text{Perimeter of the first shape = 17 ft}$
$\text{This is not equal to 18 ft.}$


$\text{Perimeter of the second shape = 18 ft}$
$\text{This is equal to 18 ft.}$


$\text{Perimeter of the third shape = 16 ft}$
$\text{This is not equal to 18 ft.}$


$\text{Perimeter of the fourth shape = 24 ft}$
$\text{This is not equal to 18 ft.}$

Therefore, option (B) is correct.
