Final answer:
34% of the rectangle is shaded with grey squares, calculated by dividing the number of grey squares (17) by the total number of squares (50) and then multiplying by 100.
Step-by-step explanation:
To find what percent of the rectangle is shaded with grey squares, you need to calculate the percentage of grey squares in comparison to the total number of squares in the rectangle. Since there are 17 identical grey squares and the total number of squares is 50, the calculation will be as follows:
- Divide the number of grey squares by the total number of squares: 17 ÷ 50.
- Multiply the result by 100 to get the percentage: (17 ÷ 50) × 100.
Performing the calculation, you get (17 ÷ 50) × 100 = 0.34 × 100 = 34%. Therefore, 34% of the rectangle is shaded with grey squares.
