Question

side length in rectangle c corresponding side length in rectangle d scale factor 2 1 2 \frac{\square}{\square} = 1 4 2 4 \frac{\square}{\square} = 2

Explanation:

Step1: Find scale - factor for first row

Let the scale - factor be $x$. We have the equation $2\times x = 1$. Solving for $x$, we divide both sides of the equation by 2. So $x=\frac{1}{2}$.

Step2: Find scale - factor for second row

Let the scale - factor be $y$. We have the equation $4\times y = 2$. Solving for $y$, we divide both sides of the equation by 4. So $y = \frac{2}{4}=\frac{1}{2}$.

Answer:

The scale - factor in the first row is $\frac{1}{2}$, and the scale - factor in the second row is $\frac{1}{2}$.
