Question

the scale factor of a figure and its enlargement is 6. what is the new length of the enlarged figure if the original length is 3 cm?
○ 3 cm
○ 6 cm
○ 18 cm
○ 36 cm

Explanation:

Step1: Recall the scale factor formula

To find the new length of an enlarged figure, we use the formula: \(\text{New Length} = \text{Original Length} \times \text{Scale Factor}\)

Step2: Substitute the given values

Given that the original length is \(3\) cm and the scale factor is \(6\), we substitute these values into the formula: \(\text{New Length} = 3 \times 6\)

Step3: Calculate the result

\(3\times6 = 18\) cm

Answer:

18 cm
