To find the area of a blanket that measures 55 inches by 43 inches, you can use the formula for the area of a rectangle, which is:
\[
\text{Area} = \text{Length} \times \text{Width}
\]
In this case, the Length is 55 inches and the Width is 43 inches. Therefore, we can write the expression as:
\[
\text{Area} = 55 \times 43
\]
However, none of the provided options directly corresponds to this expression. Let's analyze the options given:
1. **492 - 62** - incorrect
2. **55² - 43²** - could be simplified but not the area; this represents the difference of squares.
3. **49² + 62** - incorrect
4. **55² + 43²** - represents the sum of the squares and not the area.
The expression that ultimately reflects the area most closely in a related context is **55² - 43²**, as it can be manipulated using the difference of squares formula, which is not quite the area but relevant in equations.
Thus, if none of the options directly calculates the area of the rectangle, **"55² - 43²"** is relevant for some cases but does not yield the area directly. The direct area calculation isn't listed among the choices. However, if we must pick from the options, select **"55² - 43²,"** though it's more about the relationship and not the area itself.
To clarify: **55 x 43** is the direct answer for the area, which isn't explicitly mentioned.
