The area is f(x).
And
f(x) = (x)(2x + 5).
Where one side has different measurement than the other side.
The situation is modeled by a rectangle which has different measurement for length and breadth.
This is a rectangle where one side is 5 feet more than twice of the shorter side.
The area is found out by multiplying length and breadth.
Area= length× breadth
If
x = breadth
of the area then the
length = 2x+5
Which means that the length is 2 times plus 5 feet greater than the breadth.
Suppose that the breadth =x=5 feet
then the length = 2x+5= 2×5+ 5= 10+5= 15 feet
This situation with an output of area in square feet is modeled by a rectangle where one side is longer than the other.
