Answer:
P = (17.2x+16.4)
Step-by-step explanation:
Given that,
Length, l = 8.6x+3
Width, b = 5.2
We need to find the expression for the perimeter of the rectangle. The formula for the perimeter of the rectangle is given by :
[tex]P=2(l+b)[/tex]
Putting values of l and b in the above formula
[tex]P=2(8.6x+3+5.2)\\\\=2(8.6x+8.2)\\\\=2(8.6x)+2(8.2)\\\\=17.2x+16.4[/tex]
So, the required perimeter of the rectangle is [tex]17.2x+16.4[/tex].
