Answer:
2
x
Step-by-step explanation:
The diagonal divides the square into 2 right angles with legs s and hypotenuse x
Using Pythagoras' identity on one of the right triangles, then
s² + s² = x²
2s² = x² ( divide both sides by 2 )
s² =
( take the square root of both sides )
s =
= 
Thus
perimeter = 4s = 4 ×
= 
Multiply numerator/ denominator by 
perimeter =
= 2
x
Answer:
40
Step-by-step explanation:
Substitute the variable, x, with 4

3(4)= 12
7(4)= 28
12 + 28 = 40
The answer is 4.782, so yes maria is correct:-)
