Question

the rectangles below are scaled copies of one another. the side that corresponds to 20 units in the original rectangle is 5 units in the scaled copy. the scale factor is \\(\frac{1}{4}\\). now, find the missing side length of the scaled copy. original rectangle (with side 20 and top side 12) scaled copy (with side 5) \\(20 \cdot \frac{1}{4} = 5\\) the scale factor is \\(\frac{1}{4}\\).

Explanation:

Step1: Identify the original side length

The original rectangle has a side length of 12 units (the top side).

Step2: Apply the scale factor

The scale factor is $\frac{1}{4}$, so we multiply the original side length by the scale factor.
$12 \times \frac{1}{4} = 3$
