Here is a map of part of Downtown Salt Lake City. You are starting at the corner of 11th Ave. and D St. (on the star).
a. If you walk East to I St., South to 7th Ave., West to D St. and then
North to your starting point, how many blocks will you have walked in
total? Describe the shape of your path.
b. Draw and describe in words at least two different ways that you can
walk exactly 8 blocks and end up where you started.
c. Jessica said the path she took on her walk enclosed a polygon that
had an area of 6 square blocks. Draw some possible shapes that her
walk could have taken. Was her path necessarily rectangular?

you need to rotate this triangle about the origin 270 degrees clockwise to create the full square.

proportions are fractions that equal to each other. so if two fractions are the same, they are proportional.

let's check the answers to see if they are proportional.

question a is not proportional because you can't turn 1.5/3 to 3/9. if you try to multiply 1.5/3 by 2 or 3, you wont get 3/9. it's impossible to make the fractions the same.

question b is not proportional because you can't turn 22/33 to 4/6. 33 can't go into 6.

question c is proportional because when you multiply 2 and 3 by 71, you would get 142/213, and those fractions equal to each other

question d is proportional because when you divide 14 and 7 by 2, you would end up with 7/3.5, and those fractions equal to each other.
