how do you find a perimeter of a rectangle
To find the perimeter of a rectangle, you need to add up the lengths of all four sides.
Here's the formula for finding the perimeter of a rectangle:
Perimeter = 2 * (length + width)
Let's understand this with an example:
Suppose you have a rectangle with a length of 6 units and a width of 4 units.
Perimeter = 2 * (6 + 4)
Perimeter = 2 * 10
Perimeter = 20
So, the perimeter of this rectangle is 20 units.
find perimeter of ractangle 8x 10
To find the perimeter of a rectangle with a length of 8 units and a width of 10 units, we can use the formula:
Perimeter = 2 * (length + width)
Plugging in the given values:
Perimeter = 2 * (8 + 10)
Perimeter = 2 * 18
Perimeter = 36
Therefore, the perimeter of the rectangle is 36 units.
To find the perimeter of a rectangle, you need to follow these steps:
1. Identify the length and width of the rectangle. These are typically given in the problem statement or can be measured if you have a physical rectangle.
2. Multiply the length of the rectangle by 2.
3. Multiply the width of the rectangle by 2.
4. Add the results from steps 2 and 3 together.
5. The sum obtained in step 4 is the perimeter of the rectangle.
For example, let's say the length of a rectangle is 6 cm and the width is 4 cm.
Step 1: Length = 6 cm, Width = 4 cm.
Step 2: Multiply the length by 2: 6 cm x 2 = 12 cm.
Step 3: Multiply the width by 2: 4 cm x 2 = 8 cm.
Step 4: Add the results together: 12 cm + 8 cm = 20 cm.
Step 5: The perimeter of the rectangle is 20 cm.
