Answer:

1. 20x+8=48 2. x=2 3. the area of the square is 144units^2

Step-by-step explanation:

assuming its a perfect 4 sides square the total perimeter would be 5x + 2 units multiplied by 4 = the perimeter so 20x+8 = 48

20x+8=48

subtract 8 from both sides

20x=40

divide 20

x = 2 units

For area plug x back into 5x+2 and you will get 12 units for one side and all sides here should be 12 units so multiply one side with another

12 x 12 = 144 units^2

Answer:

Well I answered in the comments, but I need points so the answers are (in order) 12, 2, and 144

Step-by-step explanation:

Since it's a square, the sides will be the same length. If the perimeter is 48, then you divide 48 by 4 and you will have 12- your answer.

For x, subtract 2 from 12 to get ten, then divide that by five to get your answer which would be 2.

If the side length is 12, you square that and 12 squared is 144.
