Question

If the length of a figure (preimage) is 6cm, how long will the new figure (image) be if you triple the length? Explain how you found your answer.

Answer 1

The length of the new image is 216 cm.

Step-by-step explanation:

The given data is that,

• The length of the previous image is 6 cm.
• The length of the new image is unknown.

To find the length of the new image :

Use the given information that the length of the new image is triple the length of the pre-image.

This means that, the length of new image = thrice the length of previous image.

⇒ triple the length = three times the length

Here, the length is given as 6 cm.

Therefore, the length of new figure = 6×6×6 = 216.

The length of the new image is 216 cm.
