    Step-by-step explanation:

    hello:

    the area of this rectangle : A = 4*m

    for m = 3 A = 4*3 = 12 U

    for m = 2.2 A = 4*2.2 = 8.8 U

    for m = 3 A = 4*1/5 = 4/5 = 0.8 U

    the area of this rectangle be 11 square units when : 4m = 11²

    m = 11²/4 U + 30.25 U

    P=12, P=8,8, P=4,5

    Step-by-step explanation:

    P=4*m, P=area

    If m=3, P=4*3=12

    if m=2,2 P=4*2,2=8,8

    if m=1/5 P=4*1/5=4/5

    if P=11 then 4*m=11, m=11/4

    The area of the rectangle is 11 if m = 11/4
