The image shows a rectangle on a grid where the task is to calculate the perimeter. The grid scale indicates that each square represents 1 cm.

Step-by-step solution:

1. Length of the rectangle: By counting the squares along the longer side (horizontal), the rectangle spans 5 squares. Since the scale is in centimeters, the length is 5 cm.

2. Width of the rectangle: By counting the squares along the shorter side (vertical), the rectangle spans 2 squares. This means the width is 2 cm.

3. Perimeter formula: The perimeter $P$ of a rectangle is given by: $P = 2 \times (\text{Length} + \text{Width})$ Substituting the values: $P = 2 \times (5 + 2) = 2 \times 7 = 14 \, \text{cm}$

Thus, the perimeter of the rectangle is 14 cm.
