The perimeter of rectangle is 100.

The formula for the perimeter of rectangle is


P=2(l+w)

The length of the rectangle is 2x-8 and width of the rectangle is x+4.

The perimeter is


100=2(2x-8+x+4)
50=3x-4
3x=54
x=18

Hence the value of x is 18.

The length is


2*18-8=36-8=28

The width is


18+4=22

The correct options are 22 and 28.
