Question

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

Explanation:

Step1: Count total and pink squares

The grid is 10x10, so total squares: \(10 \times 10 = 100\).
Pink squares: First 7 columns (7) times 10 rows, minus 0 (since first 7 columns are full for 10 rows? Wait, looking at the grid: first 7 columns (each with 10 squares) and then? Wait, no—wait, the pink part: let's count. Wait, the grid is 10 columns (since 10x10). Wait, the pink area: columns 1 - 7? Wait, no, looking at the image: the pink is 7 columns (width 7) and 10 rows? Wait, no, wait the grid: let's see, the total grid is 10x10 (10 columns, 10 rows). The pink part: let's count the number of pink squares. Let's do row by row. Rows 1 - 10: in each row, first 7 squares? Wait, no, wait the image: the pink is 7 columns (7 squares per row) for 10 rows? Wait, no, wait the 4th row (from top) has a pink square, then the next rows: wait, no, maybe I miscounted. Wait, actually, the grid is 10 columns (x-axis) and 10 rows (y-axis). Let's count the pink squares:

First, the total number of squares in the grid: \(10 \times 10 = 100\) (since it's a 10x10 grid, 10 columns, 10 rows).

Now, count the pink squares: Let's see, the pink area: columns 1 to 7 (7 columns) and rows 1 to 10? Wait, no, wait the 4th row (row index 4, starting from top) has a pink square, then row 5: pink, ..., row 10: pink. Wait, actually, looking at the grid, the pink part is 7 columns (width 7) and 10 rows? Wait, no, maybe 7 columns for the first 4 rows, then 6 columns? No, that's not right. Wait, maybe the grid is 10x10, and the pink squares are 7 columns (7) times 10 rows? Wait, no, let's count:

Wait, the grid has 10 columns (each column has 10 squares). Let's count the number of pink squares:

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

Wait, that's 7 10 = 70? Wait, no, that can't be. Wait, maybe the pink is 7 columns (7) and 10 rows? Wait, but 710=70. Wait, but 70 out of 100 is 70%. Wait, but maybe I made a mistake. Wait, no—wait, the grid: let's check the number of white squares. White squares: 3 columns (columns 8 - 10) times 10 rows: 310=30. So total squares: 70 + 30 = 100. So pink squares: 70. Therefore, percentage is (70/100)100 = 70%.

Wait, that makes sense. So total squares: 1010=100. Pink squares: 7 columns 10 rows = 70. So percentage is 70%.

Step2: Calculate percentage

Percentage = (Number of pink squares / Total squares) * 100
Number of pink squares = 70, Total = 100
So (70 / 100) * 100 = 70%

Answer:

70%
