Answer:
Area of Rectangle = 
Step-by-step explanation:
Rectangle two vertices lie on x axis ; two vertices lie on parabola
.
Supposing coordinates of upper right vertex of rectangle are P = 
Due to parabola symmetry, width of rectangle is twice the distance horizontal (X) axis distance between Y axis & point P.
Width of rectangle = 
Length of rectangle =
; 
Area of Rectangle = Length x Width
= 
= 
= 
80 divided by 2.5 is 32, if this is the entire question.
I think its 149/ 490. Not sure, but pretty confident. Hope this helps.
