Area and volume SAT question

The correct answer is $2,048$. The area $A$, in square inches, of a rectangle is equal to the product of its length $l$, in inches, and its width $w$, in inches, or $A=lw$. It's given that the rectangle has a length of $64$ inches and a width of $32$ inches. Substituting $64$ for $l$ and $32$ for $w$ in the equation $A=lw$ yields $A=(64)(32)$, or $A=2,048$. Therefore, the area, in square inches, of the rectangle is $2,048$.
