Explanation:

Step1: Count total grid squares

The grid is 10 columns × 10 rows, so total squares = $10 \times 10 = 100$.

Step2: Count blue grid squares

Count the blue squares: $10 + 3 = 13$.

Step3: Calculate percentage

Percentage = $\frac{\text{Blue Squares}}{\text{Total Squares}} \times 100\% = \frac{13}{100} \times 100\% = 13\%$.

Answer:

13%
