Answer
Find out the perimeter of the isosceles triangle.
To prove
As shown in the figure.
P(0,4) , Q(-2,0) and R(2,0) are the vertices of the triangle PQR.
Formula

As P(0,4) and Q(-2,0)


In the isoceles triangle the two sides of the triangles are equal .
Therefore PQ = PR

As Q(-2,0) and R(2,0)


QR = 16 unit
