Answer:
1. 24 2. 65 3. 6.5
Explanation:
1. You break it in half and do the algortim bxh/2 . First would be 4x2/2 is 4 and 4x10/2 is 20. Add them and you get 24.
2. This would have 3 parts, 2 triangles and 1 square. the square would be 6x5 which is 30. the 2 triangles will be the same area so to find out what to divide 5 by, you would do 13-6= 7. 7x5=35 which will equal both triangles. 30+35=65
3. bxh/2 so 4x3.25 is 13 and that /2 is 6.5
