If it's a rectangle, mutliply each one by 2.
27 cm.
The answer is 28 cm.
If the shape measuring 8 centimeters by 5 centimeters is a rectangle, the perimeter of the rectangle is 25 centimeters (2w + 2l)
The perimeter would be 26cm.
The perimeter of that closed image would be 21 centimeters. Thank you and have a lovely day!
46 centimeters
74 cm.
2 x (8 + 3) ie 22cm
Each side is 8cm so the perimeter is 4*8 = 32 cm
9 cm
It's 22.4 cm! 3.2+3.2+8+8= 22.4. Check it on a calculator.
To find the perimeter of a nonagon (a nine-sided polygon), you multiply the length of one side by the number of sides. Given that each side is 4.8 centimeters, the perimeter is calculated as (9 \times 4.8) centimeters, which equals 43.2 centimeters. Therefore, the perimeter of the nonagon is 43.2 centimeters.
