Answer:
Step-by-step explanation:
The LED screen of the camera is rectangular in shape.
Given the length of the screen = 4/x+6
Width of the screen = 3/x-1
Area of the LED screen = Length * Width = 4/x+6 * 3/x-1
On simplification, Area = 12/(X+6)(X-1)
= 12/x²-x+6x-6
= 12/x²+5x-6 units²
Perimeter of the LED screen = 2(L+W)
= 2(4/x+6 + 3/x-1)
= 2(4(x-1)+3(x+6)/x+6(x-1))
= 2(4x-4+3x+18/x²+5x-6)
= 2(7x+14/x²+5x-6)
= 14(x+2)/x²+5x-6 units
