Answer: 128 
Step-by-step explanation:
Let the width be W then the length will be 2W since it is twice as long as it width.
The formula for calculating the perimeter of a rectangle is given by :
P = 2 ( L + W )
48 = 2 ( W + 2W )
48 = 2(3W)
48 = 6W
Divide through by 6
Therefore:
W = 48/6
W = 8 inches
This means that the Length is 2 x 8 = 16 inches
Area = Length x breadth
Area = 16 x 8
Area = 128 
Answer:
The 2nd, 3rd, and last equations could be a possible first step.
The rest are no's.
Step-by-step explanation:
In the second equation, the 3 was distributed.
In the 3rd, it was separately distributed.
In the last, both sides were divided by 3.
The rest are knows because every equation gives us enough information.
