Vaughn paints his porch floor and also the porch floors of 9 neighbors. Each floor is a rectangle that is 8. 2 feet long and 6.
Burka [1]

Part a: The correct option A. 8.2 × 6.7  = 54.94; 54.94 x 9 = 494.46 square feet, for the equation of area.

Part b: Exact total area all 9 Vaughn paints = 494.46 square feet.

<h3>Explain the term the area of the rectangle?</h3>
  • The territory a rectangle occupies inside its 4 sides or limits is known as its area.
  • A rectangle's sides determine its area. In essence, the breadth and length of both the rectangle multiplied together gives the area of the rectangle.

As the equation stated-

Length of the rectangular porch floor = 8.2 feet

Width  = 6.7 feet

Part a: The most accurate estimation of the total area of all of the other painted porch floors comes from Vaughn paints.

Area = length x width

Equation for the total area is;

Area = 8.2 x 6.7 = 54.94 square feet.

There are 9 neighbor's floor also

Thus, equation becomes.

Area =  54.94 x 9 square feet.

Part b: Every one of the porch floors which Vaughn paints combined.

Area =  54.94 x 9 square feet.

Area =  494.46 square feet.

Thus, every one of the porch floors which Vaughn paints combined is 494.46 square feet.

The correct question are-

Vaughn paints his porch floor and also the porch floors of 9 neighbors. Each floor is a rectangle that is 8. 2 feet long and 6. 7 feet wide.

Part A: Which equations represent the best estimate of the total area of all the porch floors that Vaughn paints?

A. 8.2 × 6.7  = 54.94; 54.94 x 9 = 494.46 square feet

B. 8 x 7 = 56; 56 x 10 = 560 square feet

C. 10 x 7 = 70; 70 x 10 = 700 square feet

D. 10 x 10 = 100; 100 x 9 = 900 square feet

Part b: What is the exact total area of all the porch floors that Vaughn paints?
