Question

what percentage of the shape is green?
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 green grid cells

Count the shaded cells: $5$

Step3: Calculate percentage

Percentage = $\frac{\text{Green cells}}{\text{Total cells}} \times 100\%$
$\frac{5}{100} \times 100\% = 5\%$

Answer:

$5\%$
