Larry wants to buy some carpeting for his living room. the length of the room is 2 times the width and the area of the room is 18 square meters. what is the length of the living room?

For this case we have that by definition, the area of a rectangular space is given by:

Where:

A: It's the area

w: It is the width

l: The length

If they tell us that and we have:

As we speak of a length, we take the positive root:

The length is:

bn,mn,n.vn.

step-by-step explanation:

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.
