The area of the new rectangle is;

Step-by-step explanation:

Given that the area of a rectangle is;

Let x and y represent the length and width;

`\begin{gathered} x* y=24 \\ xy=24 \end{gathered}`

If the length and width of the rectangle are multiplied by 5;

`\begin{gathered} A=5x*5y \\ A=25xy \end{gathered}`

recall that;

`xy=24`

so, we have;

Therefore, the area of the new rectangle is;
