Split the shapes into rectangles, then multiply width by height.
1. A = 9 * 24 + 5 * 6 = 216 + 30 = 246 units²
2. (assuming all angles are right) A = 3 * 35 + 25 * 8 = 105 + 200 = 305 units²
Or, find the area of the larger rectangle, subtract area of negative space.
3. A = 30 * 18 - 26 * 6 = 540 - 156 = 384 units ²
