Answer:
Step-by-step explanation:
Given points P and Q have same x-coordinate but different y- coordinates.
The distance between P and Q is the difference of y- coordinates:
- PQ = 4 - (-4) = 8 units = 8 cm
The area is 64 cm², it means the adjacent sides are
a)
If the points R and S are to the left, their coordinates are
- S = (-1 - 8, 4- 0) = (- 9, 4)
- R = (-1 - 8, - 4 - 0) = (- 9, -4)
b)
If the points R and S are to the right, their coordinates are
- S = (-1 + 8, 4 + 0) = (7, 4)
- R = (-1 + 8, - 4 + 0) = (7, -4)
