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?

Answer 1

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.
