Answer:
The coordinates of the image trapezoid are
A"(-4,5), B''(-1,5), C''(0,3), D''(-5,3)
The pre-image was first reflected in the line y=x, so the mapping will be
The resulting coordinates were then translated 4 units right;
For A''(-4,5), y+4=-4 and x=5
This means y=-8, x=5
Hence A(5,-8)
For B''(-1,5), y+4=-1, and x=5.
This means y=-5 and x=5
B(5,-5)
For C''(0,3), C(3,-4)
For D''(-5,3), D(3,-9)

Answer:
Scale of the new blueprint: 2 inches = 2.5 feet (or 4 inches = 5 feet)
Width of the new blueprint: 14.4 inches
Step-by-step explanation:
To solve this problem we can use rules of three to find each of the questions: blueprint's new scale and new width.
To find the new scale, we can find the real length of the patio first:
2 inches -> 3 feet
14 inches -> X feet
2/14 = 3/X
X = 21 feet
Now we can use this value to create the new scale:
16.8 inches -> 21 feet
2 inches -> X feet
16.8/2 = 21/X
X = 2*21/16.8 = 2.5 feet
So the new scale is 2 inches = 2.5 feet, or 4 inches = 5 feet
Now, to find the new width of the blueprint, we can do the following rule of three:
14 inches of length -> 16.8 inches of length
12 inches of width -> X inches of width
14/12 = 16.8/X
X = 12*16.8/14 = 14.4 inches
