To find the ratio of the length of the blue rectangle to the length of the green rectangle, we need to know the dimensions (length and width) of both rectangles.
Let's assume the length of the blue rectangle is L1 and the length of the green rectangle is L2. Similarly, let's assume the width of the blue rectangle is W1 and the width of the green rectangle is W2.
1. Length Ratio: The ratio of the length of the blue rectangle to the length of the green rectangle can be calculated by dividing L1 by L2. The ratio is expressed as L1/L2.
2. Width Ratio: The ratio of the width of the blue rectangle to the width of the green rectangle can be calculated by dividing W1 by W2. The ratio is expressed as W1/W2.
3. Perimeter Ratio: The ratio of the perimeters of the blue and green rectangles can be calculated by dividing the sum of the lengths and widths of the blue rectangle by the sum of the lengths and widths of the green rectangle. The ratio is expressed as (2*L1 + 2*W1) / (2*L2 + 2*W2).
4. Area Ratio: The ratio of the areas of the blue and green rectangles can be calculated by dividing the product of the length and width of the blue rectangle by the product of the length and width of the green rectangle. The ratio is expressed as (L1 * W1) / (L2 * W2).
To find the specific ratio values, you need the length and width measurements of both the blue and green rectangles.
