    Answer: 4m + 3

    Step-by-step explanation:

    This is because the perimeter of a triangle is the same as adding all of its sides.

    3m + (4-m) + (2m-1)

    Group like terms:

    (3m-m+2m) + (4-1)

    Then combine like terms to get your final answer of:

    4m + 3

    perimeter = 4m + 3

    the perimeter is the sum of the 3 sides of the triangle, thus

    perimeter = 3m + 4 - m + 2m - 1 = 4m + 3
