Nữa chu vi bức tranh :
16,8 : 2 = 8,4 ( m )
Chiều dài bức tranh :
( 8,4 + 3,2 ) : 2 = 5,8 ( m )
Chiều rộng bức tranh :
5,8 - 3,2 = 2,6 ( m )
Diện tích bức tranh :
5,8 x 2,6 = 15,08 ( m2 )
Dùng hết số giấy màu :
15,08 : 1 x 0,75 = 11,31 ( kg )
đ/s : 11,31 kg

60 bức tranh được chọn treo ở triển lãm (trong đó có 46 bức đoạt giải) đã làm nên một phòng tranh đẹp : màu sắc tươi tắn, bố cục rõ ràng, ý tưởng hồn nhiên, trong sáng mà sâu sắc.
