A rectangle has a width that is 50% of its length. The length of the rectangle is 12 inches. What is the area of the rectangle. (Help!!)

72 inches²

Step-by-step explanation:

Let be equal to the width of the rectangle.

Let be equal to the length of the rectangle.

Plug in 12 inches as the length

Therefore, the width of the rectangle is 6 inches.

Plug in 12 inches as the length and 6 inches as the width.

Therefore, the area of the rectangle is 72 inches².

I hope this helps!

for the friend request.

when a figure, such as triangle (xyz) is reflected over the line y = x to create x'y'z' the x-coordinates and y-coordinates of the original image (pre-image) will be reversed for the image. (e.g., (x, y) > (y, x)) this means that the pre-image position of the x- and y-coordinates switch places which in turn provides a mirror like image of the original xyz.  

i notice that when i draw a line segment from x to x', that the points are parallel from each other -- they are exactly across from each other and do not intersect with any other points.  

yes, think i would see the same characteristic if you drew the line segment connecting y with the reflecting line and then y' with the reflecting line because of the essence of reflections. because it is a mirror image, each point was effected the same way which leads me to conclude that they same would apply to y and y'.
