2 answers:
Answer: 90
Step-by-step explanation:
Given : The number of fertilizer types = 6
The number of temperature zones =5
The number of water treatments=3
The number of different lawn plots =
Hence, the number of different lawn plots she needs in order to test each fertilizer type, temperature range, and water treatment configuration =90

A 90 degree counter-clockwise rotation is being done on the black figure to get the red figure.
The algebraic rule for a 90 degree counter-clockwise rotation is
For instance, the point C = (0,1) moves to C' = (-1,0), which is shown in the graph given and also you can use the rule above to get the same coordinates. The other points A,B and D follow the same rule.
Side note: the rotation is centered at the origin (0,0). This point is fixed.
