SAT Question f3f06c3a: Area and Volume answer and explanation with Desmos solution

Choice C is correct. It’s given that $x=7$ centimeters and $y=5$ centimeters for the rectangle. The area, $A$, of a rectangle can be found using the formula $A=lw$, where $l$ represents the length and $w$ represents the width. In this rectangle, $x$ represents the length and $y$ represents the width. Substituting $7$ for $l$ and $5$ for $w$ in the equation yields $A=\left(7\right)\left(5\right)$, or $A=35$. Therefore, the area of the rectangle is $35$ square centimeters.
