Solution

Area of the rectangle = length x breadth

A. Write an equation to showing relationship between x and y:


\begin{gathered} \text{Area = length x breadth} \\ A=l\text{ x b} \\ A_1=3x \\ A_2=2y \end{gathered}
\begin{gathered} A_1+A_2=30_{} \\ 3x+2y=30 \end{gathered}

The equation for the relationship between x and y is

3x + 2y = 30
