Mathematics
1 answer:
xxMikexx [17]2 years ago

Answer:

  • 8x² + 8x - 2

Step-by-step explanation:

<u>We know that:</u>

  • Perimeter of a rectangle = Sum of all its sides
  • Length of rectangle = 4x² - x + 2
  • Width of rectangle = 5x - 3

To find the perimeter, we need to use the equation "Perimeter of a rectangle = Sum of all its sides".

<u>Solution:</u>

  • Perimeter of a rectangle = Sum of all its sides
  • => 2[{4x² - x + 2} + {5x - 3}] = Perimeter
  • => 2[4x² - x + 2 + 5x - 3] = Perimeter
  • => 2[4x² + {-x + 5x} + {2 - 3}]
  • => 2[4x² + 4x - 1]
  • => 8x² + 8x - 2

Hence, the perimeter of the rectangle is 8x² + 8x - 2.
