Rhombus has 2 axes of symetry (they contain diagonals).
If rhombus is a square then has 4 axes of symetry.
Answer:
√85
Step-by-step explanation:
s=[√d1)²+(d2)²]/2
s=(√12²+14²)/2
a=(√340)/2
s=(2√85)/2
s=√85
The equation of the parabola in vertex form

Given :
vertex (3,2), point (2,-4)
The vertex form of parabola is 
Where (h,k) is the vertex
Given vertex is (3,2). so, h=3 and k=2
Replace it in the equation

Now we find out the value of 'a' using the given point (2,-4)
Point (2,-4) is (x,y)
x=-2 and y=-4
Replace it in the equation we got to find out 'a'
