Math Problem Statement

For each oftwo rectangles,the ratio of the rectangle's length to i; width is 6 to 5.The width ofrectangle Xis 19.1 times the width

frectangle Y. How does the length ofrectangle Xcompare to the length ofrectangl

Y?

The length ofrectangle Xis 0.83times the length ofrectangle Y

The length ofrectangle X is 1.2times the length ofrectangle Y

The length ofrectangle Xis 19.1times the length ofrectangle Y.

The length ofrectangle X is 22.92times the length ofrectangle Y.

Solution

Let's solve the problem step by step.

Given:

  1. The ratio of the length to the width for both rectangles X and Y is LW=65\frac{L}{W} = \frac{6}{5}.
  2. The width of rectangle X is 19.1 times the width of rectangle Y, i.e., WX=19.1×WYW_X = 19.1 \times W_Y.

To Find:

We need to determine how the length of rectangle X compares to the length of rectangle Y.

Solution:

  1. Step 1: Express the lengths in terms of widths:

    Since the ratio of length to width for both rectangles is 65\frac{6}{5}, we can express the lengths of the rectangles as: LX=65×WXL_X = \frac{6}{5} \times W_X LY=65×WYL_Y = \frac{6}{5} \times W_Y

  2. Step 2: Substitute WX=19.1×WYW_X = 19.1 \times W_Y into the equation for LXL_X:

    LX=65×(19.1×WY)L_X = \frac{6}{5} \times (19.1 \times W_Y)

  3. Step 3: Simplify to compare LXL_X with LYL_Y:

    LX=19.1×65×WYL_X = 19.1 \times \frac{6}{5} \times W_Y LX=19.1×LYL_X = 19.1 \times L_Y

Conclusion:

The length of rectangle X is 19.1 times the length of rectangle Y.

Correct Answer:

The length of rectangle X is 19.1 times the length of rectangle Y.
