Question

The length of a rectangle is 2 meters less than 3 times the width. The perimeter is 60 meters. Find the width.The width ismeters.

Answer 1

Step 1

Let x= the width

`3x-2=length`

(because the length is 2 meters less than 3 times the width)

Step 2

The perimeter of a rectangle is given as;

`\begin{gathered} P=2length+2width \\ P=2(3x-2)+2x \\ P=60 \end{gathered}`
`\begin{gathered} 60=6x-4+2x \\ 60=8x-4 \\ 60+4=8x \\ x=8m \end{gathered}`

Answer;

`Width=8m`
