SAT Question 575f1e12: Area and Volume answer and explanation with Desmos solution

The area, $A$, of a rectangle is given by $A=lw$, where $l$ is the length of the rectangle and $w$ is its width. It's given that the length of the rectangle is $34$ centimeters (cm) and the width is $29$ cm. Substituting $34$ for $l$ and $29$ for $w$ in the equation $A=lw$ yields $A=\left(34\right)\left(29\right)$, or $A=986$. Therefore, the area, in square centimeters, of this rectangle is $986$.
