17. If a square has side s, what is the formula for it's area? 

18. Similar to 17, what is the formula for the radius of a circle with radius r? 

Once you have the formulas, you can set them equal to what the question gives you and solve!

@adoredelano look here
the area of square formula is length multiply with width ( l x w ) 
so |dw:1410831123133:dw|

25

anonymous · Answer

Area = x^2 = 625
x^2 = 625
x^2-625 = 0

(x-25)(x+25)= 0
Positive answer:
x = 25
