A right rectangle and a right triangle prism have the same height. If the lenght of the side of the rectangle base is twice the width, explain how to determine the area of the triangular base in terms of the rectangle base length.

What is a "right rectangle" ????

Check your typing, your question makes no sense to me.

ahhh, now you changed the wording.

Let the width of rectangle be x

then its length is 2x

Volume of rectangular prism = (2x^2)(h)

Volume of triangular prism = Area of base(h)

area of base = Volume of triangular prism/h

= Volume of triangular prism/(Volume of rectangular prism/2x^2)

= 2x^2(Volume of triangular prism)/(Volume of rectangular prism

Do the two prisms have the same volume ?

Check your question again.
