Answer
$8$ square inches
Work Step by Step
The area $A$ of a rectangle is given by the formula $A=lw$ where $l$ is the length and $w$ is the width.
Substitute the given values into the formula to obtain:
$A=(4\text{in.})(2\text{in.})$
$A=8\text{in.}^2$
Hence, the area of the rectangle is $8$ square inches.
