Question

what percentage of the shape is blue?
write your answer using a percent sign (%).

Explanation:

Step1: Count total grid cells

The grid is $10 \times 10$, so total cells = $10 \times 10 = 100$

Step2: Count blue grid cells

Top 5 full rows: $5 \times 10 = 50$; Partial row: 4 blue cells. Total blue = $50 + 4 = 54$

Step3: Calculate percentage

Percentage = $\frac{\text{Blue Cells}}{\text{Total Cells}} \times 100\%$
$\frac{54}{100} \times 100\% = 54\%$

Answer:

54%
