Marissa is painting her rectangular patio, with the exception of a bench that does not need to be painted: rectangle with a leng
Vesnalui [34]

The area of the rectangular patio to be painted is: B. A = (x + 20)(x + 10) - 12.

<h3>What is a Rectangle?</h3>

A rectangle, by definition, is a quadrilateral with two pairs of opposite that have the equal lengths. All four angles of a rectangle are right angles (90 degrees).

<h3>What is the Area of a Rectangle?</h3>

The area of a rectangle = (length of rectangle)(width of rectangle).

Given the following parameters for the patio and the bench:

  • Length of rectangular patio = x + 20
  • Width of rectangular patio = x + 10
  • Length of rectangular bench = 6
  • Width of rectangular bench = 2

Area to be painted = area of rectangular patio - area of rectangular bench

Area of rectangular patio = (x + 20)(x + 10)

Area of rectangular bench = (6)(2) = 12

Area to be painted = (x + 20)(x + 10) - 12

The answer is: B. A = (x + 20)(x + 10) - 12.
