Question

Write a simplified polynomial expression that can be used to represent the perimeter of the rectangle. 3x-7 and x-7​

Answer 1

P = 8x-28

Explanation:

Given that,

Length = (3x-7)

Width = (x-7)

We need to find the perimeter of the rectangle. The formula for the perimeter of a rectangle is given by :

`P=2 (l+b)\\\\P=2(3x-7+x-7)\\\\P=2(4x-14)\\\\P=8x-28`

So, the perimeter of the rectangle is equal to 8x-28.
