The length of a small rectangle is 9in and 8in respectively. The length of the large rectangle is 24in. If the length and width of the two rectangles have the same ratio, what is the width of the large rectangle?

Final answer:

To find the width of the large rectangle with the same ratio as the small rectangle, we set up a proportion based on their lengths and widths which results in 9/8 = 24/w. Solving for w gives us 21.33 inches as the width of the large rectangle.

Step-by-step explanation:

The width of the large rectangle can be determined by using the ratio of the lengths and widths of the rectangles. Since the length of a small rectangle is 9 in and the width is 8 in, the ratio of length to width for the small rectangle is 9:8. Given that the ratio remains the same for the large rectangle, and its length is 24 in, we can set up a proportion to find its width.

Let w be the width of the large rectangle. The proportion based on the ratios is:

\(\frac{9}{8} = \frac{24}{w}\)

Now, cross-multiply to solve for w:

8 \(\times\) 24 = 9 \(\times\) w
192 = 9w
w = \(\frac{192}{9}\)
w = 21.33 in

Therefore, the width of the large rectangle is 21.33 inches, maintaining the same length-to-width ratio as the small rectangle.
