    Ok so first find circumference then find perimiter then area

    c=2pir

    15=r

    c=2pi15

    c=30pi

    so that means that the perimiter of the square=30pi

    perimiter of circle=4 times measure of 1 side

    30pi=4 times measue of 1 side

    divide oth sides by 4

    30pi/4=1 side

    area=side times side since all sides are equal measue

    area = (30pi/4) times (30pi/4)

    area = (900pi^2/16)

    area = (225pi/4) cm^2

    if you aprox pi to 3.14

    area = (225 times 3.14) / 4

    area=176.625 cm^2
