1. Area Review

2. Quadrilaterals Squares, rectangles, or parallelograms Trapezoid A = bh
A = ½(b1+b2)h

3. Quadrilateral Practice

4. Triangles
Note: the height, h, is not always a side length. h must be perpendicular to the base
Example 2: h is not a side, it is inside the triangle
Example 3: h is not a side, it is outside the triangle
Any type of triangle
A = ½ bh
Example 1: h b h b h b

5. Triangle Practice

6. Hexagons
There are many ways to get the area of a hexagon depending on which measurements you are given
For our formula, look at ways you can split a hexagon into more familiar shapes

7. Hexagon Area Formula Steps used to derive the formula:
Find the area of one triangle
There are six triangles. Therefore we must multiply the area of one triangle by six
Formula for area of a hexagon: 6 * area of 1 triangle
= 6 * ½ bh
= 3bh
