A rectangular mural measures 238 centimeters by 435 centimeters. Raegan creates a new mural that is 27 centimeters longer.
What is the perimeter of Raegan's new mural?
9
centimeter(s)
To find the perimeter of the new mural, we need to add up all the sides.
The length of the new mural is 238 centimeters + 27 centimeters = 265 centimeters.
The width and height are still the same, so they are 435 centimeters each.
The perimeter is the sum of all sides: 435 cm + 435 cm + 265 cm + 265 cm = 1400 cm.
Therefore, the perimeter of Raegan's new mural is 1400 centimeters.
Len has a rectangular wooden deck that measures 14 feet by 25 feet. He builds an addition to the deck that makes it 6 feet longer.
What is the perimeter of his deck now?
feet
To find the new perimeter of Len's deck, we need to add up all the sides.
The original length of the deck is 25 feet, and the original width is 14 feet.
Len builds an addition that makes the deck 6 feet longer, so the new length is 25 feet + 6 feet = 31 feet.
The original width remains the same at 14 feet.
The perimeter is the sum of all sides: 14 ft + 14 ft + 31 ft + 31 ft = 90 ft.
Therefore, the new perimeter of Len's deck is 90 feet.
To find the perimeter of Raegan's new mural, we need to add up all four sides of the rectangle.
The length of the new mural is 238 centimeters + 27 centimeters = 265 centimeters.
The width of the new mural remains the same at 435 centimeters.
The perimeter of the new mural is therefore 2 * (length + width) = 2 * (265 cm + 435 cm) = 2 * 700 cm = 1400 cm.
So, the perimeter of Raegan's new mural is 1400 centimeters.
To calculate the perimeter of Raegan's new mural, we need to add up the lengths of all four sides of the rectangle.
Given that the original mural measures 238 centimeters by 435 centimeters, the new mural will have the same width of 238 centimeters but a length that is 27 centimeters longer.
To find the length of the new mural, we add 27 centimeters to the original length:
Original length + 27 centimeters = 435 centimeters + 27 centimeters = 462 centimeters
Now, we can calculate the perimeter by adding up the measurements of all four sides:
Perimeter = Length + Width + Length + Width
Substituting the known values:
Perimeter = 462 cm + 238 cm + 462 cm + 238 cm
Calculating the sum:
Perimeter = 1400 cm
So, the perimeter of Raegan's new mural is 1400 centimeters.
