The area of a rectangle can be calculated as the product of the width and length
[tex]A=wl[/tex]From this expression, you can calculate the width, by dividing both sides of it by the length
[tex]\begin{gathered} \frac{A}{l}=\frac{wl}{l} \\ \frac{A}{l}=w \end{gathered}[/tex]If the area is A=104cm² and the length is 8cm, the width is:
[tex]\begin{gathered} w=\frac{A}{l} \\ w=\frac{104}{8} \\ w=13 \end{gathered}[/tex]The width of the rectangle is 13cm
