The length of a rectangle is 3x−4 units, and the area is 3x^2+2x−8 square units. In terms of x, what is the perimeter of this rectangle in units?

Question

Find the perimeter of the rectangle in units using the given information

Answer 1

The other side would be the other factor of the are 3x^2+2x-8 which would be (x+2)

So the sides are (x+2) and (3x-4)

Therefore the perimeter is

2(x+2) +2(3x-4)= 2x+4 +6x-8= 8x -4
