༒ Here's your Answer ~
❖ What we need to know before we solve ~
❝ Area of a rectangle is ❞ = ❝ Length × Width ❞
✠ Given terms :
➺ Area = 27 cm²
➺ length = 9 cm
✠ Now, let's assume the width to be ❝ x cm ❞ and proceed to find its value using given relation ~
![\qquad \: \twoheadrightarrow\sf Area = L × B](https://img.qammunity.org/2023/formulas/mathematics/high-school/2nxjea1twyc62nhyvoo5a76580qudss18g.png)
![\qquad \: \twoheadrightarrow\sf 27 = 9 × x](https://img.qammunity.org/2023/formulas/mathematics/high-school/q47dakbid9lxkw659hz0jizfhd4fiai3z4.png)
![\qquad \: \twoheadrightarrow \sf x = 27 ÷ 9](https://img.qammunity.org/2023/formulas/mathematics/high-school/ajwwyjl2w0awf8td5sj8nsrl5fsfzjkcht.png)
![\qquad \: \twoheadrightarrow \sf \: x = 3 \: cm](https://img.qammunity.org/2023/formulas/mathematics/high-school/vdrts1uf0kyfim55vs4dcrqnluj9bcac26.png)
✠ Therefore, The width of the rectangle = 3 cm
