Use proportions to find the missing side length x in the two similar figures length 4.23 yd and side length of 3.25 yards

We can set up a proportion between the corresponding side lengths of the two similar figures:

$\frac{x}{4.23}=\frac{3.25}{y}$

To find the missing side length $x$, we need to solve for it. We can do this by cross-multiplying and then dividing:

$x\cdot y = 4.23\cdot 3.25$

$x = \frac{4.23\cdot 3.25}{y}$

Since $y$ is not given, we can't solve for $x$ using the proportion provided.
