In order to calculate the length of the rectangle, we can use the formula for the area of a rectangle:
[tex]A=L\cdot W[/tex]Where A is the area, L is the length and W is the width.
If the area is equal to 19.68 cm² and the width is equal to 4.8 cm, let's calculate the length:
[tex]\begin{gathered} 19.68=4.8\cdot L\\ \\ L=\frac{19.68}{4.8}\\ \\ L=4.1\text{ cm} \end{gathered}[/tex]Therefore the length of the rectangle is equal to 4.1 cm.
