Question

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

Explanation:

Step1: Count total and pink squares

Total squares: \( 5 \times 10 = 50 \). Pink squares: First row 5, next 4 rows 4 each. So \( 5 + 4\times4 = 5 + 16 = 21 \)? Wait, no, wait. Wait, the grid: let's check again. Rows: 5 rows, columns: 10 columns. First row: 5 pink (columns 1 - 5), rows 2 - 5: each has 4 pink? Wait no, wait the first row: 5 pink (columns 1 -5), then rows 2,3,4,5: columns 1 -4? Wait no, looking at the grid: first row: 5 pink (columns 1 -5), then rows 2,3,4,5: each has 4 pink? Wait no, maybe I miscounted. Wait, let's count again. Let's see the grid:

Row 1: 5 pink (columns 1 -5), 5 white (columns 6 -10)
Row 2: 4 pink (columns 1 -4), 6 white? No, wait the image: first row: 5 pink (left 5), then rows 2 -5: each has 4 pink? Wait no, maybe the first row is 5, and rows 2 -5 are 4 each? Wait 5 + 44 = 5 + 16 = 21? No, wait 5 rows: row 1: 5, rows 2 -5: 4 each. So 5 + 44 = 21? Wait no, 5 rows: row 1: 5, rows 2,3,4,5: 4 each. So total pink: 5 + 4 + 4 + 4 + 4 = 21? Wait no, 5 + 44 = 5 + 16 = 21. Total squares: 510 = 50. Wait, no, 5 rows, 10 columns: 510=50. Wait, but 5 + 44: row 1:5, rows 2-5:4 each (4 rows), so 5 + 44=21. Then percentage is (21/50)100 = 42%? Wait, no, wait maybe I miscounted the pink squares. Wait let's look again. Wait the first row: 5 pink (columns 1-5), then rows 2,3,4,5: each has 4 pink? Wait no, maybe the first row is 5, and rows 2-5 are 4 each? Wait 5 + 4*4 = 21. 21/50 = 0.42, so 42%. Wait, but maybe I made a mistake. Wait let's count again. Let's list each row:

Row 1: columns 1-5: pink (5), columns 6-10: white (5)
Row 2: columns 1-4: pink (4), columns 5-10: white (6)
Row 3: columns 1-4: pink (4)
Row 4: columns 1-4: pink (4)
Row 5: columns 1-4: pink (4)
So total pink: 5 + 4 + 4 + 4 + 4 = 21. Total squares: 510=50. So percentage is (21/50)100 = 42%. Wait, but maybe I miscounted. Wait, maybe the first row is 5, and rows 2-5 are 4 each, so 5 + 4*4=21. 21/50=0.42, so 42%. Yes, that seems right.

Step2: Calculate percentage

Percentage = \( \frac{\text{Number of pink squares}}{\text{Total number of squares}} \times 100 \)
Number of pink squares = 21, Total squares = 50
So \( \frac{21}{50} \times 100 = 42\% \)

Answer:

42%
