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
