On a bicycle trail, the city is painting arrows like the one shown below:

Upper pointing arrow with height of 11 and length of 9. Rectangular base of arrow has length of 7 and height of 8. All units are in centimeters.

Calculate the area of the arrow by decomposing it into rectangles and triangles.

66.5 square centimeters
69.5 square centimeters
83 square centimeters
99 square centimeters

both equations and proportions are better.

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'.

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.
