 The perimeter of a rectangle is the distance around the
outside of the rectangle. A rectangle has four sides
with opposite sides being congruent. The formula for
finding the perimeter is Side A + Side B + Side A +
Side B.
 Formula= 2(L+B).
To calculate the perimeter of an object or space, you
will need to add the length and width, then multiply
by 2.
( 2 + 4 ) x 2 = ______

 The perimeter of a square is the distance
around the outside of the square. A square has
four sides of equal length. The formula for
finding the perimeter of a square is 4*(Length
of a Side).
 Formula= 4* side.
To find the
perimeter
of a square,
multiply
the side by
4.

Finding the area of a triangle is different.
Area of a triangle = ½ (base x height)
***(Base x height) is the same as (length x width).***

Sometimes it makes it easier to remember
if you can imagine it like this:
3
4
A triangle is half of a
rectangle or square. This is
because the base (4) x the
height (3) would be the
same as the length x the
width of a rectangle.
