Answer:
If the rope is 20 ft long, then the maximum area the cow can graze is:
r^2 square feet.
is approximately 3.14, so that means we have: 3.14(20^2) = 1256 ft squared.
Thus, the maximum area that the cow can graze is 1256 ft squared.
Let me know if this helps!

Basic Proportionality Theorem:
If a line is parallel to a side of a triangle which intersects the other sides into two distinct points, then the line divides those sides in proportion.
i.e
...........{Basic Proportionality Theorem}
Substituting the given values we get
The value of x = 15.
Step-by-step explanation:
A=a+b
2h=13+10
2×18=207
formula a=a+b/2×18

From the given equation, -3x² - x - 3 = 0
where a = -3, b = -1, c = -3
Now substitute for the values in the formula above
x = -(-1) ± √(-1)² - 4(-3)(-3)
