1. Find the area of the parallelogram. Areas of Parallelograms and Triangles LESSON 8-1 The area of the parallelogram is 26.4 square inches. = 26.4 Simplify. = 8  3.3Substitute 8 for b and 3.3 for h. A = b  hUse the formula for the area of a parallelogram. Additional Examples

2. A park is a triangular plot of land. The plot has a base of 214 m and a height of 70 m. What is the area of the plot? Areas of Parallelograms and Triangles LESSON 8-1 The area of the triangle is 7,490 square meters. A = b  hUse the formula for the area of a triangle. 1212 =  214  70Substitute 214 for b and 70 for h. 1212 = 7,490 Simplify. Additional Examples

3. Areas of Parallelograms and Triangles LESSON 8-1 Find the area of the figure. Area of the larger rectangle: 3  12 = 36, or 36 m 2 The total area is 10 + 36 + 10, or 56 square meters. Area of the smaller rectangle: 2  5 = 10, or 10 m 2 Find the area of each polygon. Split the polygon into two rectangles and a triangle, as shown by the dashed lines. Area of the triangle: (5  4) = (20), or 10 m 2 1212 1212 Additional Examples
