8. Area of Triangles Area of a triangle = ½ x base x height A = 1/2bh LOOK FOR THE RIGHT ANGLE TO DEFINE BASE AND HEIGHT…. ALWAYS!!!!!!!!!!!!!!!!!!!

9. “FIND THE AREA OF THE SHADED PORTION” 1.Find the area of the large shape. 2.Find the area of the small shape. 3.Subtract them 4.Label your answer. 5 in. 10 in. 2 in. 6 in. (5 )(10) = 50 (2)( 6) = 12 50 – 12 = 38 38 in 2

10. Try these… 7 in. 12 in. 5 in. 8 in. Large area = (7)(12) = 84 Small area = ½(5)(7) = 17.5 Subtract them = 66.5 Label…. 66.5 sq. in. 9 ft. 14 ft. 16.6 ft. 7.5 ft. Large area = (9)(14) = 126 Small area = ½(9)(11) = 49.5 Subtract them = 76.5 Label…. 76.5 sq. ft. 11 ft.
