solve for the width in the formula for the area of a rectangle. use the rewritten formula to find the width of a rectangle with an area of 42 square inches and a length of 16.8 inches.

Answer

Explanation:

Step1: Recall area formula

The area formula of a rectangle is $A = lw$, where $A$ is area, $l$ is length and $w$ is width. We want to solve for $w$.

Step2: Isolate width variable

Divide both sides of the equation $A = lw$ by $l$ (assuming $l\neq0$). We get $w=\frac{A}{l}$.

Step3: Substitute given values

Given $A = 42$ square - inches and $l = 16.8$ inches. Substitute into the formula $w=\frac{A}{l}$, so $w=\frac{42}{16.8}$.

Step4: Calculate the result

$\frac{42}{16.8}=2.5$ inches.

Answer:

2.5 inches
