14.
Width of the rectangle
= (Area of the rectangle) / (Length of the rectangle)
= (20x² + 49x + 30) / (4x + 5) in
= (4x + 5)(5x + 6) / (4x + 5) in
= 5x + 6 in
Area of the shaded area
= [(5x + 6) - 5x] * 5 in²
= 6 * 5 in²
= 30 in²

Area of the rectangle:
20x^2 + 49x + 30
= (4x + 5)(5x + 6)
Area of the shaded region:
30 inches^2
20x^2 + 49x + 30
= (4x + 5)(5x + 6)
Area of the shaded region:
30 inches^2
