Q9:THE PERIMETER OF THE SQUARE IS ;
8 X 4 = 32 ( CM )
SO , THE PERIMETER OF THE RECTANGLE IS 32 CM .
HALF OF THE RECTANGLE IS :
32 : 2 = 16 ( CM )
THE WIDTH OF THE RECTANGLE IS :
16 : ( 3 + 1 ) X 1 = 4 ( CM )
THE LENGTH OF THE RECTANGLE IS :
4 X 3 = 12 ( CM )
ITS AREA IS :
12 X 4 = 48 ( CM 2)
ANSWER : 48 CM 2
Q10: THE COST FOR 12 PEOPLE TO EACH OF A MOVIE KET IS :
5 X 12 = 60 ( DOLLARS )
THE COST OF A SOFT DRINK IS :
72 - 60 = 12 ( DOLLARS )
ANSWER: 12 DOLLARS

1) The rectangle has length p and breath q (cm), where p and q are intergers. If p and q satisfy the equation pq+q=13 + q2
then the maxnium area of the rectangle
2) Let a,b and c be positive intergers such that ab + bc=518 and ab-ac=360. Find the largest value of the product abc.
P/s: As you may now, These are some questions from the 8 round of Math Violympic. Plz help me as much as you can! Thanks for all!
Ta có: \(pq+q=13+q^2\Leftrightarrow q\left(p+1\right)=13+q^2\)
Vì\(q^2⋮q\Leftrightarrow13⋮q\Leftrightarrow\left[{}\begin{matrix}q=1\\q=13\end{matrix}\right.\)
Nếu q =1 thì:\(p+1=14\Leftrightarrow p=13\)
\(\Rightarrow pq=13\left(cm^2\right)\)(1)
Nếu q=13 thì:\(13p+13=182\Leftrightarrow p=13\)
\(\Rightarrow pq=169\left(cm^2\right)\)(2)
Từ (1)(2) ta có: \(max\left(pq\right)=169\left(cm^2\right)\)

Give a rectangle such that its width is a hlf as its length. The ratio of the perimeter of the rectangle to its width is ...
Cho một hình chữ nhật mà chiều rộng của nó là một nửa chiều dài. Tỉ lệ giữa chu vi của hình chữ nhật với chiều rộng của nó là ?
Bài giải:
Gọi chiều rộng là: R; chiều dài là D; Chu vi là CV của hình chữ nhật
Theo đề bài ta có: R=1/2D. Suy ra D=2R
Mà chu vị hình chữ nhật là: CV = (D+R)x2.
Tỉ lệ giữa chu vi của hình chữ nhật với chiều rộng là: CV:R = (2R +R)x2 : R
= 3Rx2:R =6
Đáp án: 6
