Area Review

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

Quadrilateral Practice

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

Triangle Practice

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

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
