    Answer: X=1.5

    Step-by-step explanation:

    Solution

    Perimeter = 2 (l+w)

    25 = 2 (3x+4 + 2x+1)

    25 = 2 (3x+2x+4+1)

    25 = 2 (5x+5)

    25 = 10x+10

    Now subtract 10 on both sides ...

    25-10 = 10x+10-10

    15=10x

    Now divide 10 on both sides to get x

    15/10 = 10x/10

    1.5=X
