SAT Question 9d2e7037: Area and Volume answer and explanation with Desmos solution

Choice D is correct. The area, $A$, of a rectangle can be found using the formula $A=lw$, where $l$ represents the length and $w$ represents the width of the rectangle. It’s given that a rectangle has a length of $56$ inches and a width of $28$ inches. Substituting $56$ for $l$ and $28$ for $w$ in the formula $A=lw$ yields $A=(56)(28)$, or $A=1,568$. Therefore, the area, in square inches, of the rectangle is $1,568$.
