(Algebra II) Which expression represents the perimeter of the rectangle above?
2 answers:
2(3x-1+3x-3)=2(6x-4)=12x-8
SO (B)12x-8 IS THE ANSWER.
Answer
The expression represented the perimeter of a rectangle be 12x -8 units .
Reason
Formula
Perimeter of rectangle = 2× (length + breadth)
As shown in the diagram
Length = (3x-1) units
Breadth = (3x-3) units
Put this in the formula
Perimeter of rectangle = 2 × (3x - 1 + 3x - 3)
= 2× (6x - 4)
= 12x -8 units
Hence Proved
