Area of a rectangle is equal to length times width so the equation:
To find w, you would solve for it in this equation by dividing by l on both sides like so:
Which leaves you with:
So to find width you divide the Area by the length:
To find w, you would solve for it in this equation by dividing by l on both sides like so:
Which leaves you with:
So to find width you divide the Area by the length:
