Molly has 3 pictures hanging on her bedroom wall. One is a 4 inch square, one is a rectangle that is 5 inches by 7 inches, and the third is a triangle with a height of 10 inches and base of 12 inches. What area of Molly’s wall is covered by pictures?

111

Step-by-step explanation:

Find the area of all the pictures. One is 16 inch square. Second is 35 inch squared. Thrid is 60 because you do base times hight and divide by 2. Add them all.

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'.
