Find the area of △XYZ by following these steps.

✓ 1. Press Continue to circumscribe a rectangle around the triangle.

✓ 2. Find the area of the rectangle. Area = 12 24 48 units²

✓ 3. Find the area of △1. Area = 3 10.5 12 units²

✓ 4. Find the area of △2. Area = 3 10.5 12 units²

✓ 5. Find the area of △3. Area = 3 10.5 12 units²

✓ 6. Subtract the areas of the three triangles from the area of the rectangle. Area = 48 − 10.5 − 12 − 3 = 21 22.5 24 units²
