Each side of the grid in the figure shown is 1 km. Estimate the perimeter of the figure.
A. 25 km
B. 8 km
C. 40 km
D. 14 km
To estimate the perimeter of the figure, count the number of squares along each side.
Top side: 5 squares
Right side: 3 squares
Bottom side: 5 squares
Left side: 3 squares
Now calculate the perimeter by adding the number of squares on each side:
5 + 3 + 5 + 3 = 16 squares
Since each side of the grid is 1 km, the estimated perimeter is 16 km.
Therefore, the closest option is:
D. 14 km
