To find the area of a rectangle, you multiply its length by its width. For Hiram's blanket, the length is 55 inches and the width is 43 inches. Therefore, the area \(A\) can be calculated as:
\[ A = \text{length} \times \text{width} = 55 \times 43 \]
None of the options provided directly represent the multiplication to find the area, but let's analyze the options given:
- 492−62 - This is not an area calculation.
- 55² + 43² - This adds the squares of the dimensions, which does not give the area.
- 49² + 6² - This is not relevant for finding the area.
- 55² − 43² - This subtracts the squares of the dimensions, which does not give the area either.
Since none of the options directly represent the correct calculation for finding the area (which should be \(55 \times 43\)), it appears that the options provided do not match the formula for calculating the area of the blanket. Therefore, none of these expressions can be used to find the area of the blanket.
