Let x = the length of each side of the square.
Therefore the dimensions of the rectangle are x and x/2.
Because the perimeter of the rectangle is 15 inches, therefore
2x + 2(x/2) = 15
2x + x = 15
3x = 15
x = 5 in.
The perimeter of the square scarf is 4x = 4*3 = 12 in.
The area of the scarf is 3*3 = 9 in²
Answer:
Perimeter = 12 in
Area = 9 in²

The correct answer is none of the ones listed. The correct answer is 18/5.
In order to find this, follow the order of operations.
−(−2−5x)+(−2)=18 ---> Distribute the negative
2 + 5x - 2 = 18 ----> Combine like terms
5x = 18 -----> Divide by 5
x = 18/5
