Example Find the perimeter of figure . Perimeter = ìììì + ìììì + ìììì + ìììì + ìììì

8 = 2.37 + 2.20 + 3.69 + 3.02 + 1.61 = 12.89 cm The perimeter of figure is 12.89 cm. Notice that the unit of measure remains unaffected. The area of a polygon is the measure of the surface area of the polygon. The calculation of the area of a polygon is dependent upon the type of polygon. Below are a few area formulas of common polygons you can expect to encounter on the TEAS exam. • Area of a Triangle = < ℎ 8 • Area of a Parallelogram (Square, Rhombus, or Rectangle) = ℎ • Area of a Trapezoid = < ℎ( < + 8 ) Examples Find the area of the triangle. Find the area of the trapezoid. 1 = 2 ℎ 1 1 1 = 2 ℎ < + 8 = 1 (2.5)(3.0 + 2.5) = 2 (5.0)(4.0) = 2 (20) = 10 cm 8 1 2 1 = 2 (2.5)(5.5) = 2 (13.75) = 6.875 cm 8 Notice when you find the area of a polygon the unit of measure becomes squared.
