Understanding Area and Perimeter
Before creating a worksheet, it is crucial to understand what area and perimeter mean in the context of a rectangle.
What is Area?
The area of a rectangle refers to the amount of space enclosed within its four sides. It is measured in square units and is calculated by multiplying the rectangle's length by its width.
Formula for Area:
\[
\text{Area} = \text{Length} \times \text{Width}
\]
For example, if a rectangle has a length of 5 units and a width of 3 units, the area would be:
\[
\text{Area} = 5 \times 3 = 15 \text{ square units}
\]
What is Perimeter?
The perimeter of a rectangle is the total distance around its edges. It is measured in linear units. The perimeter can be calculated by adding together the lengths of all four sides or using a formula that incorporates the length and width.
Formula for Perimeter:
\[
\text{Perimeter} = 2 \times (\text{Length} + \text{Width})
\]
Using the same example, if the rectangle has a length of 5 units and a width of 3 units, the perimeter would be:
\[
\text{Perimeter} = 2 \times (5 + 3) = 2 \times 8 = 16 \text{ units}
\]
