Answer:
Dimensions of rectangle : Width =
, Length = 
Area of Rectangle = 
Step-by-step explanation:
A rectangle constructed with its base on the x-axis and two of its vertices on the parabola
Supposing coordinates of upper right vertex of rectangle are P = 
Due to parabola symmetry, width of rectangle is twice the horizontal (X) axis distance between Y axis & point P.
Width of rectangle : 
Length of rectangle : 
Area of Rectangle = Length x Width
