USING CORRECT UNITS
PERIMETER: Is the distance around a figure.
in + in + in + in = in
AREA: Is the square units that cover a figure.
length • width = in • in = in2
VOLUME: The number of cubic units inside a figure.
length • width • height

3. Area of a Parallelogram
# 3
To find the area for a parallelogram use what you know about area of a rectangle.
A = base x height
3 in
A = b x h
5 in
A = 5 x 3
= 15 in2

4. Area of a Triangle # 4 A = base x height A = 8 x 6
A triangle is half the area of a rectangle.
To find the area of a triangle you use the rectangle formula and divide it in half.
A = base x height 2
6 m
8 m
A = 8 x 6
= 24 m2 2

5. Area of a Trapezoid A = (b1 + b2) x h A = (4 + 5) x 3 2 A = (9) x 3 27
# 5
4 ft
A = (base1 + base2) x height
3 ft 2
A = (b1 + b2) x h
5 ft 2
A = (4 + 5) x 3 2
A = (9) x 3 27 =
= 13.5 ft2 2 2

16. #10 Perimeter of a Triangle
Perimeter: Distance around a geometric figure.
When you add the
sides, you are also
adding the units.
When you add units,
your UNITS DO NOT
CHANGE!
You must include units in every answer!
