Answer:
1) 6+7=42
2) Beginning (0,0,-25) end (0,-20,-25)
Step-by-step explanation:
1) Plot these point on graph. By this you can determine the fourth coordinate(-3,4) as it is a rectangle.
So, length =7
breadth =6
area =7*6 =42
2) Here height of rack is 25 feet thus it's Z coordinate is -25.
It moved 20 feet south along Y axis thus Y coordinate = -20
No movement in X thus x coordinate =0
Thus , beginning (0,0,-25) end (0,-20,-25)
