Answer:
The perimeter of rectangle is 22x+4 feet.
Step-by-step explanation:
Width of rectangle = 7x-7 feet
Length of rectangle = 4x+9 feet
We need to find perimeter of rectangle.
The formula used is:
[tex]Perimeter\: of\: rectangle=2(Length+ Width)[/tex]
Now, putting values and finding perimeter
[tex]Perimeter\: of\: rectangle=2(Length+ Width)\\Perimeter\: of\: rectangle=2(4x+9+ 7x-7)\\Perimeter\: of\: rectangle=2(4x+7x-7+9)\\Perimeter\: of\: rectangle=2(11x+2)\\Perimeter\: of\: rectangle=22x+4\:feet[/tex]
So, the perimeter of rectangle is 22x+4 feet.
