A rectangular mural measures 1.3 feet by 4.8 feet. Harmonoy creates a new mural that is 0.6 feet longer. What is the perimeter of his new mural?
The original mural has a perimeter of 1.3 + 1.3 + 4.8 + 4.8 = 12.2 feet.
The new mural is 0.6 feet longer, so the new length is 1.3 + 0.6 = 1.9 feet.
Therefore, the new width is still 4.8 feet.
The perimeter of the new mural is 1.9 + 1.9 + 4.8 + 4.8 = 12.4 feet.
