2. its not letting put an answer

3. 8+8+4+4 for rectangle with perimeter of24

4. a perimeter of 24 has sides of 8+8+4+4 with an area of 32

5. 36 a 6 in square

6. the greatest area of a rectangle with 24 units is 20 units.

7. P=24 units

l=4
w=6

so 6 x 4= 24

8. 9. P= 5+7+5+7=24
w=7
L=5
A= 7×5=35 units

10. I got the answer 36 units.

11. 12. 6 by 6 works because a square can be a rectangle but a rectangle isn’t a square

13. 6 by 6 because 6+6+6+6=24 and 6×6=36

14. 8+8+4+4=26

15. Isabella Mendoza
