Answer:
C
Step-by-step explanation:
since line AB and CD make all right angles (given) angles 6+7+8 will equal 90 degrees.
According to the verticle angles rule:
angle 2 is equal to angle 6
angle 3 is equal to angle 7
angle 4 is equal to angle 8.
which proves that angle 2+4+7=90 degrees
All you do is add up all of the side lengths, and you got the perimeter.
Use the proportion inches per miles.
.5 in / 2 miles = 2.75 in / d miles
Hope this helps :)
The answer is 38 to the power of 2
