Answer:
A= 8
B= -5
C= -14
Explanation:
Area of Rectangle = length * width
Area of the shaded Rectangle:
Area = l * w
Area= (4x + 1) (3x - 5)
Open the brackets
A= 12x^2 - 20x + 3x - 5
A = 12x^2 - 17x - 5
Area of the Unshaded:
The Unshaded portion is a square. Hence, it's area = l^ 2
Area = (2x - 3) ( 2x - 3)
A= 4x^2 - 6x - 6x + 9
A= 4x^2 - 12x + 9
To get the exact shaded portion
A(Shaded) = (12x^2 - 17x - 5) - ( 4x^2 - 12x + 9)
Area = 8x^2 - 5x - 14
A= 8
B= -5
C= -14
