To determine the correct equation for the area of a rectangular plot of land given the area is 300 square feet, we need to look at the format of the equations provided and think about how area is calculated for rectangles, which is typically length multiplied by width.
The relevant options provided are:
- \( 15(x + 10) = 300 \)
- \( 15(6 + x) = 300 \)
- \( 15x = 300 \)
- \( 15(6) + x + 15(4) = 300 \)
Assuming in this context that "15" represents one dimension (e.g., width), and the missing dimension can be expressed in terms of \( x \) (e.g., length), we are looking for an equation where the product of these two dimensions equals the area of 300.
The equations break down as follows:
- The first equation suggests that one dimension is 15 and the other dimension is \( x + 10 \).
- The second suggests that one dimension is 15 and the other dimension is \( 6 + x \).
- The third implies that one dimension is 15 and that dimension is multiplied by \( x \). This means the other dimension would necessarily be \( 20 \) (since \( 15x = 300 \) implies \( x = 20/15 \)).
- The fourth option suggests the equation combines multiple dimensions and isn’t structured purely as \( A = L \times W \).
Since we need a simple multiplication to yield the area (300), the most likely candidates are the first three equations.
If the width is 15, we can find the length (expressed as \( x \) in these scenarios) that equates to the area of 300 square feet.
Among the three scenarios where \( 15 \) is multiplied by an expression yielding 300, the same form suggests a straightforward calculation of area.
Given that area = Length × Width = \( 300 \) square feet, the choices that set this up directly are:
- \( 15(x + 10) = 300 \)
- \( 15(6 + x) = 300 \)
- \( 15x = 300 \)
Any of these can apply depending on what's defined as length vs width. The equation that best represents a direct calculation to find \( x \) is typically \( 15x = 300 \) which leads to the simplest terms with one dimension missing.
However, if \( x \) is meant to be combined with another number indicating a length, we'd want either:
- \( 15(x + 10) = 300 \) indicating you are finding the length \( 10 + x \)
- \( 15(6 + x) = 300 \) indicating you are building off a base of \( 6 + x \) which could make sense in the context.
Thus, without more context, and if forced to select one most generally utilized equation for a missing length based on the dimensional products for the rectangular area, I would lean toward:
15x = 300 as the simplest and most straightforward approach to find \( x \).
