What is the formula to calculate the perimeter of rectangle PQRS?
The formula to calculate the perimeter of a rectangle is:
Perimeter = 2(length + width)
- Step 1: Identify the length and width of rectangle PQRS.
- Step 2: Add the length and width of PQRS together.
- Step 3: Multiply the sum by 2 to calculate the perimeter.
Example: | |
---|---|
Length of PQRS: | 10 units |
Width of PQRS: | 5 units |
Perimeter: | 2(10 + 5) = 2(15) = 30 units |

Perimeter Calculation Formula
The perimeter of a rectangle is the total distance around the outside of the rectangle. For rectangle PQRS, this is calculated using the formula: Perimeter = 2 × (Length + Width).
- Step 1: Measure the length (PQ or SR) and the width (QR or PS) of the rectangle.
- Step 2: Add the length and the width.
- Step 3: Multiply the sum by 2 (since a rectangle has two lengths and two widths).
This formula is derived from the fact that a rectangle has four sides with opposite sides being equal in length. Therefore, the perimeter is twice the sum of its length and width.
Component | Description |
Length (PQ, SR) | One of the longer sides of the rectangle. |
Width (QR, PS) | One of the shorter sides of the rectangle. |
Perimeter | The total distance around the rectangle. |
For example, if the length (PQ) of a rectangle is 10 meters and the width (QR) is 5 meters, the perimeter would be 2 × (10 + 5) = 30 meters.
