Question

The length of each square tile is 1 unit. Determine the perimeter of the given figure.

• A. 14 units
• B. 12 units
• C. 3 units
• D. 16 units

Answer 1

The correct option is D 16 units

Let us find the perimeter of the given figure.
● Perimeter of a closed figure = Sum of the lengths of all sides
● The perimeter of the figure is the sum of the lengths of the highlighted borders (as shown below).


● Length of the side of each square tile = 1 unit
● Number of highlighted sides = 16 sides
● Perimeter of the figure = Length of one side Number $\times$ of highlighted sides
$=1unit\times 16$
$=16units$
The perimeter of the polygon is 16 units.

Hence, option C is the correct answer.
