Answer 1

The perimeter of a rectangle is 130 ft.

Let x be the length of the rectangle and y be the width of the rectangle.

Then,

`\begin{gathered} 2(x+y)=130 \\ x+y=65\ldots\ldots(1) \end{gathered}`

Lenght is 9 feet shorter than width. Therefore,

`x=y-9\ldots\ldots(2)`

Put equation (2) in (1) implies,

`\begin{gathered} y-9+y=65 \\ 2y=74 \\ y=37 \end{gathered}`

Then, the value of x is ,

`\begin{gathered} x=37-9 \\ x=28 \end{gathered}`

Therefore, the dimensions are 28 and 37.
