Question

what is the missing length in the scaled copy?
?
units
original
25
40
scaled copy
50
?

Explanation:

Step1: Find the scale factor

The original height is 25 units, and the scaled copy height is 50 units. The scale factor \( k \) is \( \frac{50}{25} = 2 \).

Step2: Apply the scale factor to the original length

The original length is 40 units. Multiply by the scale factor: \( 40 \times 2 = 80 \).

Answer:

80
