20. An iron wire is bent into a circle which radius is 21. If the wire is now bent into a rectangle, what is the maximum value of area of it? (Take phi = 22/7)
Cari panjang kawat dulu,
keliling lingkaran : π × d
22/7 × 42 = 132 cm
keliling persegi panjang :
(p + l) × 2
132 : 2 = p + l
66 cm = p + l
Berarti jumlah p + l = 66 cm
kemungkinan paling besar adalah
66:2 = 33
p = 33 + 1 = 34
l = 33 - 1 = 32
Luas = 34 × 32
