Question

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

Explanation:

Step1: Count total and green squares

Total squares: \(10 \times 10 = 100\). Green squares: First 9 rows have 2 each, 10th row has 1. So \(9\times2 + 1 = 19\).

Step2: Calculate percentage

Percentage = \(\frac{19}{100} \times 100\% = 19\%\)

Answer:

19%
