Answer:

Step-by-step explanation:
Height of the Rectangle
Width of the Rectangle
Area of the Rectangle = Height X Width

The area of the rectangle is 
Dy/dx=-2x+15
d2y/dx2=-2
Since the acceleration is a constant negative it has an absolute maximum value for y(x), thus it opens downward, as x decreases without bound as x approaches ±∞
AB is congruent to side DE.
So,
AB= 23 and DE= 23
I hope this helps!
