Step-by-step explanation:
Perimeter of a rectangle = 6x + 8
Solution:
Given area of a rectangle =
Let us first factor the given polynomial.
Taking out common terms in the above expression
Taking out common term in the above expression
Area of a rectangle = l × b
Therefore, and
Perimeter of a rectangle = 2(l + b)
The answer is same if you take <em>l</em> = x + 3 and <em>b</em> = 2x + 1.
Hence, perimeter of a rectangle = 6x + 8.
