Question

1) On a city map drawn on a coordinate plane, the city park is located at (20, 4) and the school is at (20, 9). What is the distance between the park and the school in the map units?
5 units

11 units

13 units

16 units

2) A rectangular plot of land is represented on a coordinate plane where each unit is one foot. The vertices are at (50, 20), (50, 90), (100, 20) and (100, 90). What is the perimeter of the rectangular plot?

120 feet

240 feet

520 feet

3500 feet

Answer 1

1) Since the x coordinates don't change, the distance is just delta y.

9-4=5 units

2)

w=dx=100-50=50

h=dy=90-20=70

p=2(w+h) so

p=2(70+50)

p=240 feet

Answer 2

1) is 5 units which can be found by graphing
2) I got 240 by graphing this one as well
