What
is
a
rectangle
?
A
rectangle
is a
two
-
dimensional
shape
with four sides and four
right
angles
.
A
rectangle is a special type of these
shapes:
Quadrilateral
:
four
sides
Parallelogram
:
quadrilateral with two pairs of parallel
sides
A
square
is a special type of rectangle. It has four right angles
and
four equal
sides.

Identify rectangles
Area
of
a
rectangle
You
can find the
area
of
a
rectangle
by multiplying the length times the
width.
Area
=
length
×
width
Let's
try it! The length of this rectangle is
5
units
.
The width of this rectangle is
10
units
.
Multiply
the length by the
width.
5
×
10
=
50
So,
the area of the rectangle is 50 square
units.

Perimeter
of
a
rectangle
You
can find the
perimeter
of any shape by adding the side lengths. Since rectangles have two pairs of equal sides, you can find the perimeter of a rectangle by multiplying the length and width by 2 and then adding those
products.
Perimeter
=
(
2
×
length
)
+
(
2
×
width
)
Let's
try it! The length of this rectangle is
5
units
.
The width of this rectangle is
10
units
.
Plug those numbers into the
equation.
P
=
(
2
×
5
)
+
(
2
×
10
)
P
=
10
+
20
P
=
30
So,
the perimeter of the rectangle is 30 units!
