To find the area and perimeter of a rectangle, you’ll need to know two key measurements: the length and the width of the rectangle.
Calculating the Area
The area of a rectangle is calculated using the formula:
Area = Length × Width
For example, if a rectangle has a length of 5 units and a width of 3 units, the area would be:
Area = 5 × 3 = 15 square units
Calculating the Perimeter
The perimeter of a rectangle is the total distance around the outside. You can find it using the formula:
Perimeter = 2 × (Length + Width)
Using the same rectangle dimensions, the perimeter would be calculated as follows:
Perimeter = 2 × (5 + 3) = 2 × 8 = 16 units
In summary, the area tells you how much space is contained within the rectangle, while the perimeter gives you the distance around it. Always remember to keep track of the units you are using when performing these calculations!
