Lisa mural is a triangle shape. Each side is 5 feet long. His friends mural is the same shape but he enlarged it to 12 feet long. What scale factor did Leo’s friend used to create the mural from the original

To find the scale factor used to enlarge the mural, you can divide the length of a side of the enlarged mural by the length of the corresponding side of the original mural.

In this case, the original mural has sides that are 5 feet long, and the enlarged mural has sides that are 12 feet long.

Scale Factor = (Length of enlarged mural) / (Length of original mural)

Scale Factor = 12 feet / 5 feet = 2.4

So, Leo's friend used a scale factor of 2.4 to enlarge the mural.
