Can you do the bottom please which it says lesson 11.9 - 11.10

1.19)

In general, the area of a rectangle is given by the formula

In our case,

The area of figure A is 16 square units, the area of B is 12 square units and the area of shape C is 12 square units.

As for the area of a rectangle, in general,

Then, in the case of each rectangle,

11.10)

Therefore, figures A and C have the same perimeter, whereas rectangles B and C have the same area.

answer: sorry i can't you.

step-by-step explanation:

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'.
