For this case we have the following data:
Area of the rectangle,
Relationship of the sides 5: 3
By definition, the area of a rectangle is given by:
Where
- a: is the longest side.
- b: it is the side of least length.
If the sides have a 5: 3 ratio, it means:
Substituting in the formula of the area, we have:
Clearing b:
