3 answers

To find the area of a rectangle, you multiply its length by its width. In this case, Hiram's blanket has a length of 55 inches and a width of 43 inches. The area can be calculated as follows:

Area = Length × Width = 55 inches × 43 inches.

None of the expressions provided correspond to the correct calculation for the area. However, if we need to express the area using the given options, we can evaluate each one:

  1. \( 49 - 6^2 \): This does not represent the area.
  2. \( 55^2 - 43^2 \): This is a difference of squares and does not give the area.
  3. \( 49^2 + 6^2 \): This does not represent the area.
  4. \( 55^2 + 43^2 \): This does not represent the area.

Therefore, if the goal was to identify an option that could represent the area directly, none of these expressions fit the criteria for calculating the area of Hiram's blanket. The correct area is found using \( 55 \times 43 \).

the answers are
49^2-6^2
55^2-43-^2
49^2+6^2
55^2+43^2

To find the area of Hiram's blanket measuring 55 inches by 43 inches, we should multiply the length (55 inches) by the width (43 inches). The area \( A \) can be expressed as:

\[ A = 55 \times 43 \]

However, looking at the expressions you provided:

  1. \( 49^2 - 6^2 \): Not related to the area calculation and doesn't give the area.
  2. \( 55^2 - 43^2 \): This represents the difference of squares, which is not the area. However, it is related through the formula for the area as follows: \[ A = (55 + 43)(55 - 43) \] which uses the difference of squares form \( a^2 - b^2 = (a - b)(a + b) \).
  3. \( 49^2 + 6^2 \): Not related to the area calculation and doesn't give the area.
  4. \( 55^2 + 43^2 \): This represents the sum of squares and does not give the area either.

Among these options, \( 55^2 - 43^2 \) is the expression related to the area when using the difference of squares, but remember, it's not a direct calculation of area.

Therefore, while none of the expressions directly provide the area, the closest relevant expression is \( 55^2 - 43^2 \), as it represents a relationship that can lead to finding the area in another context.
