side = s, area = s^2

circle

circumference = c, area = pi d^2/4 = c^2/(4pi)

4s + c = 35 so c = (35-4s)

a = s^2 + c^2/(4pi)

a = s^2 + (35-4s)^2/(4pi)

a = s^2 + (1225-280s+16s^2)/12.56

a = 2.27s^2 - 22.3 s + 97.5

that is a parabola, find the vertex or use calculus (I used calculus)

0 = 4.54 s -22.3

s = 4.91

c = 35-4*4.91 = 15.3
