Question

Marissa is painting her rectangular patio, with the exception of a bench that does not need to be painted: rectangle with a length of x plus 20 and width of x plus 10 with a rectangle in the bottom right corner labeled bench that has a length of 6 and width of 2 write an equation to determine the area, a, of the patio that will be painted. a = (x 20)(x 10) 12 a = (x 20)(x 10) − 12 a = (x 26)(x 12) a = (x 14)(x 8)

Answer 1

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

What is a Rectangle?

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).

What is the Area of a Rectangle?

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.
