Volumes with Cross Sections: Squares/Rectangles Practice Test

Choose the correct volume setup: base bounded by $x=0$, $x=1$, $y=0$, and $y=3x$, rectangles perpendicular to $x$-axis with height twice the base.

Base bounded by $y=2-x$ and $y=0$ on $0,2$; rectangles perpendicular to $x$-axis have height $x$: which setup is correct?
