(Area of Polygons and Composite Figures MC)

A maintenance worker needs to wax a restaurant floor shaped like the image shown.

A six-sided figure. There is a horizontal base of 35 feet then another horizontal base below it of 20 feet. The longest side is to the right and is 40 feet. The top is 30 feet. There is a perpendicular from the vertex of the top to the first base of 35 that is labeled 15 feet.

If the wax cost $1.38 a square foot, how much will the wax cost to cover the floor?

$1,224.75
$1,569.75
$2,104.50
$2,449.50
Question 6(Multiple Choice Worth 2 points)

(Area of Polygons and Composite Figures MC)

A composite figure is shown.

A five-sided figure with two parallel bases. The top one is 4 inches. The vertical height between these bases is 2.3 inches. That vertical height intersects the bottom base, leaving 2.5 inches between it and the vertex to the left. The side on the right is the longest at 5.2 inches. There is a horizontal line connecting the vertex of the bottom base to the 5.2-inch side and that line is 3 inches.

Which of the following represents the total area of the figure?

16.425 in2
20.775 in2
24.15 in2
28.5 in2
Question 7(Multiple Choice Worth 2 points)

(Area of Polygons and Composite Figures MC)

An image of a rhombus is shown.

A rhombus with a base of 21 centimeters and a height of 17.3 centimeters.

What is the area of the rhombus?

363.3 cm2
181.65 cm2
176.6 cm2
38.3 cm2

Answer 1

Explanation:

First one (see diagram ) add the three areas to find total area

187.5 + 150 + 800 = 1137.5 ft^2

then:

1137.5 ft^2 * $ 1.38 /ft^2 = $ 1569.75

Second one :

See diagram..... add the labeled areas together
