1. AREA AND PERIMETER
OF SQUARE,
RECTANGLES, AND
PARALLELOGRAMS

2. Area & Perimeter
 Perimeter: the distance around the shape
 Area: the two-dimensional space inside the
shape

3. How do you find the perimeter and area of any shape?
USE YOUR FORMULA CHART!
You don’t have to memorize any formulas, just LOOK at
the formula chart to find the formula.
1.
3m Perimeter Area
P = 2b +2h A = bh
3m
P = 2(3) + 2(3) A = 3(3)
2
P = 12 m A = 9m

4. 2.
Perimeter Area
13 mm P = 2b +2h A = bh
P = 2(13) + 2(7) A = 13(7)
2
P = 40 mm A = 91m
7 mm

5. A parallelogram is a little harder to find on the
formula chart. If you cut the triangle off of the left
side and put it on the right side, what shape do
you get? Look at your formula chart.
3. Area
7 mm 5 mm
A = bh
12 mm A = 12(5)
2
A = 60mm
The base and height of any shape
ALWAYS forms a right angle in the shape.

6. P = 4s
11 cm
P = 4(11)
11 cm
P = 44 cm
A = bh
A = 11(11)
A = 121 cm
2

7. P = 2b + 2h
10 m
P = 2(10) + 2(4)
4m
P = 28m
A = bh
A = 10(4)
A = 40m
