Unformatted text preview: A triangle (which can be formed by splitting a parallelogram in half) has a similar area formula: A = ½ bh. Example A= ½ bh A= ½ (30)(10) A= ½ (300) A= 150 km 2 Complex Figures Use the appropriate formula to find the area of each piece. Add the areas together for the total area. Example  27 cm  10 cm 24 cm Split the shape into a rectangle and triangle. The rectangle is 24cm long and 10 cm wide. The triangle has a base of 3 cm and a height of 10 cm. Solution Rectangle A = lw A = 24(10) A = 240 cm 2 Triangle A = ½ bh A = ½ (3)(10) A = ½ (30) A = 15 cm 2 Total Figure A = A 1 + A 2 A = 240 + 15 = 255 cm 2 Homework Time...
