The perimeter of an object is equal to its sides added up. Because this is a triangle, it will have 3 equal sides. Since the triangle has 3 equal sides, its perimeter will be equal to one of its side lengths * 3.
Because the perimeter will be equal to one of its side lengths * 3, x is equal to one of the triangle's side lengths.

The path that Gloria follows when she jumped is a path of parabola.
The equation of the parabola that describes the path of her jump is 
The given parameters are:


<em>Assume she starts from the origin (0,0)</em>
The midpoint would be:



So, the vertex of the parabola is:

Express properly as:
