Question from Nina, a student: The length and the width of the rectangle is in the ration 5:3. Its area is 375m2. Find its perimeter. |
Hi Nina,
Suppose the length is $L$ meters and the width is $W$ meters. The fact that "The length and the width of the rectangle is in the ration 5:3." means that
\[\frac{L}{W} = \frac{5}{3}.\]
What equation do you get from the area statement? Solve these equations for $L$ and $W.$
