The perimeter of a rectangle is the sum of all sides of the rectangle. The value of x in the given rectangle is 13.5
Given that:
[tex]L = 3x + 5[/tex] --- Length
[tex]W = x - 9[/tex] --- Width
[tex]P = 100[/tex] --- Perimeter
We have:
[tex]P = 2l + 2w[/tex]
So, the expression becomes
[tex]100 = 2 \times(3x + 5) + 2 \times (x - 9)[/tex]
Divide through by 2
[tex]50 = 3x + 5 + x - 9[/tex]
Collect like terms
[tex]3x + x = 50 - 5 + 9[/tex]
[tex]4x = 54[/tex]
Divide through by 4
[tex]x = 13.5[/tex]
Hence, the value of x is 13.5
