Answer:
3: is 24 in
4: is 20 in
Explanation:
3* if you add 20+20=40 so 40-64=24 so that is the base
4* the height meaning how tall which is 20 in tall so the answer would be 20
7* is 120 in length of the border
5* is 15 because if one side is 15 cm and your total is 30 cm the other side would be 15 cm as well but you should still draw this one out to make sure you understand it ok
Hope this helps ^-^ !!!!!
