    Answer:

    25/4

    Step-by-step explanation:

    perimeter is total length of all side

    height =2(x+2) (×2 bcause has 2 side)

    length =2(3x-1) (×2 bcause has 2 side)

    2x+4+6x-2=52

    8x-2=52

    8x=50 (8x is 8 times x, so move to the other side become divide)

    x=50/8

    simplify

    x= 25/4
