Question

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

Explanation:

Step1: Count total and blue squares

The grid is a 10x10 square, so total squares = \(10\times10 = 100\).
Count blue squares: Let's calculate. Rows 1 - 12? Wait, no, 10 rows. Let's count columns. First 6 columns (since from column 1 - 6, and rows 1 - 12? Wait, no, 10 rows. Wait, let's count:

First, the blue part: Let's see, the grid has 10 columns and 10 rows (total 100 cells). Let's count the blue cells. Let's do row by row:

Row 1: 6 blue (columns 1 - 6)
Row 2: 6 blue
Row 3: 6 blue
Row 4: 6 blue
Row 5: 6 blue
Row 6: 6 blue
Row 7: 6 blue
Row 8: 6 blue
Row 9: 6 blue
Row 10: 6 blue? Wait, no, wait the image: Wait, maybe I miscounted. Wait, actually, looking at the grid, the blue area is 6 columns (width 6) and 10 rows? No, wait, no. Wait, let's check again. Wait, the white area is 4 columns (columns 7 - 10) and 10 rows? Wait, no, columns: 1 - 6 (blue), 7 - 10 (white). Rows: 1 - 10. Wait, but in some rows, maybe? Wait, no, the grid is 10x10. Let's count blue cells: 6 columns × 10 rows? Wait, no, wait the first row: 6 blue, 4 white. Second row: 6 blue, 4 white. ... Up to row 10: 6 blue, 4 white? Wait, no, looking at the image, maybe the blue is 6 columns (width 6) and 10 rows (height 10), so 6×10 = 60? Wait, no, wait the last row: 6 blue? Wait, no, the last row (row 12? No, 10 rows). Wait, maybe I made a mistake. Wait, total cells: 10×10 = 100. Let's count white cells: columns 7 - 10 (4 columns) and rows 1 - 10 (10 rows), so 4×10 = 40. So blue cells = 100 - 40 = 60? Wait, no, wait the white area: let's count white cells. Let's see, columns 7 - 10 (4 columns) and rows 1 - 10 (10 rows). So 4×10 = 40 white cells. So blue cells = 100 - 40 = 60. Wait, but wait, maybe some rows have less? Wait, no, the grid is 10x10. So if white is 4 columns (each row has 4 white cells), 10 rows: 4×10 = 40. So blue is 100 - 40 = 60. So percentage is \(\frac{60}{100} \times 100\% = 60\%\). Wait, but wait, maybe I miscounted. Wait, let's check again. Let's count blue cells:

Row 1: 6 (columns 1 - 6)
Row 2: 6
Row 3: 6
Row 4: 6
Row 5: 6
Row 6: 6
Row 7: 6
Row 8: 6
Row 9: 6
Row 10: 6

Total blue: 6×10 = 60. Total cells: 10×10 = 100. So percentage is \(\frac{60}{100} \times 100 = 60\%\).

Step2: Calculate percentage

Percentage = \(\frac{\text{Blue Cells}}{\text{Total Cells}} \times 100\% = \frac{60}{100} \times 100\% = 60\%\).

Answer:

60%
