Q&A: Calculating the Perimeter of a Rectangle

Q: What is the perimeter of a rectangle? A: The perimeter of a rectangle is the total distance around the outside of the rectangle. It is calculated by adding up the lengths of all four sides.

Q: How do I calculate the perimeter of a rectangle? A: To calculate the perimeter of a rectangle, you need to add up the lengths of all four sides. The formula for the perimeter of a rectangle is: Perimeter = 2(length + width).

Q: What is the length and width of the rectangle in this problem? A: The length of the rectangle is 31.40cm and the width is 23.70cm.

Q: How do I calculate the perimeter of this rectangle? A: To calculate the perimeter of this rectangle, we need to plug in the values for the length and width into the formula: Perimeter = 2(length + width).

Q: What is the calculation for the perimeter of this rectangle? A: The calculation for the perimeter of this rectangle is: Perimeter = 2(31.40 + 23.70) = 2(55.10) = 110.20cm.

Q: Which alternative indicates the correct perimeter of the rectangle? A: The correct alternative is A) 110.20cm.

Perimeter Calculation Steps:

Identify the length and width of the rectangle: The length of the rectangle is 31.40cm and the width is 23.70cm.
Plug in the values into the formula: Perimeter = 2(length + width)
Calculate the sum of the length and width: 31.40 + 23.70 = 55.10
Multiply the sum by 2: 2(55.10) = 110.20
The perimeter of the rectangle is: 110.20cm

Conclusion:

Calculating the perimeter of a rectangle is a simple process that involves adding up the lengths of all four sides. By using the formula Perimeter = 2(length + width), we can easily calculate the perimeter of a rectangle. In this problem, the perimeter of the rectangle is 110.20cm, which is option A.
