1. A rectangular room measures 12 feet by 20 feet. It is going to be covered with carpeting that sells for $8.35 per square foot. a. What is the area of the room in square feet?

b. How much would it cost to carpet the floor?

a). 240sqft b). $2004 (+ labor I guess)

Step-by-step explanation:

the room is rectangular, so it's area is the product of the dimensions

12feet * 20feet = 240sqft

The cost is $8.35 per sqft, so we get

240sqft * $8.35/sqft = $2004

A: 240

B: 1,980

Step-by-step explanation:

Finding the area of a 2d rectangle WxL, So it's 12x20 is 240.

I did 8.35 times the square footage, 240, and gotten 1,980.

∞ this is your sign

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.
