Question

How to find the width of a rectangle when length and area is given?

Answer 1

Area of a rectangle is equal to length times width so the equation:

$A = lw$

To find w, you would solve for it in this equation by dividing by l on both sides like so:

$\frac{A}{l}= \frac{lw}{l}$

Which leaves you with:

$w = \frac{A}{l}$

So to find width you divide the Area by the length:

$w = \frac{A}{l}$
