Area & Perimeter Formulas
Area (A) is the amount of square units of space an object occupies.
Perimeter (P) is the distance around a figure.
| 1.Square: A quadrilateral (4-sided figure) with four 90o (right) angles and four equal sides.  |
2. Triangle: A 3-sided figure |
3. Rectangle: A quadrilateral with four
90o (right) angles. |
4. Right Triangle: triangle with a 90o
(right) angle   |
5. Parallelogram: A quadrilateral with
equal opposite sides. |
|
| 6. Trapezoid: A quadrilateral with exactly
one pair of parallel sides.
|
