Question

The width of a rectangle is represented by 4x, and its length is represented by (3x+2). Write a polynomial for the perimeter of the rectangle.

Answer 1

2(7x + 2)

Explanation:

Perimeter of a Rectangle = 2 x Length + 2 x Width.

Given Length = 4x, Width = 3x + 2,

Perimeter of Rectangle = 2(4x) + 2(3x + 2)

= 8x + 6x + 4

= 14x + 4 (Degree one polynomial)

= 2(7x + 2)
