To answer this question, we can proceed as follows:
1. We know that the area of a rectangle is given by:
2. And we have that:
• The ,length, is 5ft more than its width ---> x + 5.
,
• The ,width, is x.
,
• The ,area of the garden, is 336 square feet.
3. Now, we have that:
4. We have to multiply the terms on the left side of the equation as follows:
5. Now we need to subtract 336 from both sides of the equation:
6. We have a quadratic equation, and we can solve it using the quadratic formula as follows:
7. From the resulting quadratic function, we have:
Then, we have:
8. From the answer, we have two possible solutions here:
9. Since the value of x = -21 is meaningless to this answer - the values for length or width cannot be negative, then the value for x = 16.
10. Now, to find the values for the width and the length, we have:
In summary, we have that:
The width of the garden is 16ft, and the length of the garden is 21ft.
