Question

Simplify an expression for the premier of the rectangle shown with length 8.6 X +3 and width 5.2

Answer 1

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 :

$P=2(l+b)$

Putting values of l and b in the above formula

$P=2(8.6x+3+5.2)\\\\=2(8.6x+8.2)\\\\=2(8.6x)+2(8.2)\\\\=17.2x+16.4$

So, the required perimeter of the rectangle is $17.2x+16.4$.
