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)}

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)}

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.
