The required dimensions are
Given:
A city planner wants to create adjacent sections for athletics and picnics in the yard of a youth center. The sections will be rectangular and will be surrounded by fencing as shown. There is
Calculation:
The area of each section is
Since the area of a rectangle is
Now,
Put
Compare the quadratic equation
Using the quadratic formula
Substitute the values in quadratic formula,
When
Similarly: when
Hence, the required dimensions are
