The rectangular floor of a classroom is 30 feet in length and 38 feet in width. A scale drawing of the floor has a length of 15 inches. What is the perimeter, in inches, of the floor in the scale drawing?

Length of the rectangular floor of a classroom = 30 feet

Width of the rectangular floor of a classroom = 38 feet

Length of the floor in a scale drawing = 15 inches

Which means, 1 inch is equal to :

Thus, 1 inch in the drawing is equivalent to 2 feet of the floor.

Then, width of floor in the scale drawing :

Thus, the width of the floor in the scale drawing = 19 inches

Perimeter of the floor in the scale drawing :

Thus, perimeter = 68 inches

Therefore, the perimeter of the rectangular floor in the scale drawing = 68 inches

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'.

answer: no

step-by-step explanation: because the big angle will spread away the 2 side that it is on and make the opposite side even longer.
