Area of the rectangle
The area of a rectangle is the product of its width and length.
Example:
What is the area of a rectangle having a length of 6 and a width
of 2?
The area is the product of these two side-lengths,
which is 6 ?2 = 12.
Perimeter of the rectangle
The perimeter of a rectangle is the sum of the lengths of all its
sides
Example:
What is the perimeter of a rectangle having side-lengths of 3 cm
and 8 cm?
Since a rectangle has 4 sides, and the opposite sides of a rectangle
have the same length, a rectangle has 2 sides of length 3 cm, and 2
sides of length 8 cm. The sum of the lengths of all the sides of the
rectangle is 3 + 3 + 8 + 8 = 22 cm.
