The following formula can be used to find the area (A) of a rectangle with a perimeter of 54 cm and length x cm:
A = x(27 - x)
Select the correct area value for a rectangle with length 11.5 cm.
A = 27 cm²
A = 178.25 cm²
A = 184.25 cm²
A = 23 cm²

Answer

To find the area using the formula A = x(27 - x) with x = 11.5 cm:

  1. Substitute x = 11.5 into the formula: A = 11.5(27 - 11.5).
  2. Calculate: A = 11.5 × 15.5 = 178.25 cm².

The correct area value is A = 178.25 cm².
