Given:
The length of the rectangle is l = 18cm.
The width of the rectangle is w = 10cm.
The objective is to find the perimeter and area.
Step-by-step explanation:
The general formula to find the perimeter of the rectangle is,
![P=2(l+w)\text{ . . . . . (1)}](https://img.qammunity.org/2023/formulas/mathematics/college/mjq3my0hfwk3chlqeotik6wkoda64h60oz.png)
On plugging the given values in equation (1),
![\begin{gathered} P=2(18+10) \\ =2(28) \\ =56\operatorname{cm} \end{gathered}]()
The general formula to find the area of the rectangle is,
![A=l* w\text{. . . . . (2)}](https://img.qammunity.org/2023/formulas/mathematics/college/vb22p5oa8rdxh0df0kpen6oqj64btvdrkj.png)
On plugging the given values in equation (2),
![\begin{gathered} A=18*10 \\ =180\operatorname{cm}^2 \end{gathered}]()
Hence, the perimeter of the rectangle is 56cm and the area of the rectangle is 180cm².
