    w = 10 in

    Step-by-step explanation:

    Perimeter is the measure of the length of all sides

    48 = 2L + 2w

    L = w + 4

    ^ use substitution

    48 = 2 (w + 4) + 2w simplify.

    48 = 2w + 8 + 2w combine like terms

    48 = 4w + 8 then subtract 8 from both sides

    40 = 4w then divide by 4 to isolate w

    10 = w
