lebar = p - 8
keliling = 2(p+l)
72 = 2(p+p-8)
72 = 2(2p - 8)
72 = 4p - 16
72 + 16 = 4p
88 = 4p
88 : 4 = p
22 = p
panjang = p = 22 cm
lebar = p - 8 = 22 - 8 = 14 cm
2( x + x-8) = 72
2x + 2x-16 = 72
4x-16 = 72
4x = 72 + 16
4x = 88
x = 88/4
x= 22 cm
Maka Panjangnya 22 cm dan lebarnya 22cm - 8 yaitu 14 cm.
