Answer:
21 square units
Step-by-step explanation:
The sides of the rectangle are aligned with the coordinate grid, so we can easily find its dimensions.
AB lies on the line y = -2, so the horizontal extent is the difference in x-values:
6 - 3 = 3
BC lies on the line x = 6, so the vertical extent is the difference in y-values:
5 -(-2) = 7
The area is the product of these two dimensions:
A = LW = (7)(3) = 21 . . . . square units
The area of the rectangle is 21 square units.
Answer:
the critical points are (0,0) , (0, 20), (12, 0) , (4,16)
Step-by-step explanation:
To consider the autonomous system


The critical points of the above system can be derived by replacing x' = o and y' = 0.
i.e.


x = 0 or 24 - 2x - y = 0 ----- (1)
Also

y( 20 -y - x) = 0
y = 0 or 20 - y - x = 0 ----- (2)
By solving (1) and (2);
we get x = 4 and y = 16
Suppose x = 0 from (2)
y = 20
Also;
if y = 0 from (1)
x = 12
Thus, the critical points are (0,0) , (0, 20), (12, 0) , (4,16)
