Answer 1

Perimeter =
`(30-(3)/(2)x)`

Explanation:

Width of the rectangle has been given as
`(5-(1)/(4)x)`.

Convert the statement into the algebraic expression,

"Length of the rectangle is twice the width"

Length = 2(Width)

=
`2(5-(1)/(4)x)`

=
`10-(1)/(2)x`

Since perimeter of a rectangle is given by the expression,

Perimeter = 2(Length + Width)

By substituting the values of length and width in the expression,

Perimeter =
`2[(5-(1)/(4)x)+(10-(1)/(2)x)]`

=
`2(15-(3)/(4)x)`

=
`(30-(3)/(2)x)`

Therefore, expression representing perimeter is
`(30-(3)/(2)x)`.
