Lee's mural is a triangular shape. Each side is 5 feet long. His friend's mural * 1 point is the same shape, but he enlarged it to 12 feet long. What scale factor did Leo's friend use to create the mural from the original?
To find the scale factor, divide the length of the enlarged mural by the length of the original mural.
Scale factor = Length of enlarged mural / Length of original mural
Scale factor = 12 feet / 5 feet
Scale factor = 2.4
Therefore, Leo's friend used a scale factor of 2.4 to create the mural from the original.
