Explanation:

Step1: Set up proportion for first triangle

$\frac{22}{18} = \frac{x}{45}$

Step2: Solve for first $x$

$x = \frac{22 \times 45}{18} = 55$

Step3: Set up proportion for second triangle

$\frac{x}{45} = \frac{99}{81}$

Step4: Solve for second $x$

$x = \frac{99 \times 45}{81} = 55$

Answer:

For the first triangle: $x = 55$ cm
For the second triangle: $x = 55$ yd
