Did you know?
Did you know that to find the new perimeter of a rectangular mural, you need to take into account the increase in length? In this case, Rosalie created a new mural that is 1.5 feet longer than the original 3.5 feet by 5.5 feet mural. To calculate the new perimeter, you should add the extra 1.5 feet to the length of 5.5 feet, which gives you a new length of 7 feet. The width remains the same at 3.5 feet. By using the formula for the perimeter of a rectangle (2 × length + 2 × width), you can determine that the new perimeter of Rosalie's mural is 2 × 7 feet + 2 × 3.5 feet, which equals 14 feet + 7 feet, giving you a total perimeter of 21 feet.
