Answer:
6 inches
Step-by-step explanation:
The perimeter formula for a square is P = 4*S
P =24
s = ?
24 = 4*S            Divide both sides by 4
24/4 = 4S/4      
S = 6

Answer:
2
Step-by-step explanation:
let the other leg be x
Using Pythagoras' identity 
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
x² + 1² = 3²
x² + 1 = 9 ( subtract 1 from both sides )
x² = 8 ( take the square root of both sides )
x =  
 
   = 
   =  ×
 ×  = 2
 = 2 ← exact value
 ← exact value
