Answer:
1)4)5
2)45
Step-by-step explanation:
1) ✓22 = 4.69041575 which is between 4 and 5
2) The area is 225ft2 area= length * length (the only one that fits here with 225 is 15) 15*15 is 225. Now that we know the sides for perimeter:
_15__
15 |. |. 15
-------
15
The question though, asks for the perimeter which is around. So you add 15 three times for the three sides and get 45ft
