The key word here is "or". If it's an OR question, you add the probabilities together. If it says "and", you multiply them together
As it is an OR question though, you add them.
So:
15 + 5 = 20%

Step-by-step explanation:

The area, A, in square yards, of a rectangular garden, is given by the function.

$A(x)=-2x^2+30x$

We know that, the area of the rectangle is given by :

$A=l\times b$

Where l is length and b is breadth

$A=-2x^2+30x\\\\A=2x\times (-x+15)$

Length = 2x

Breadth = (15-x)

For zeoes,

$2x\times (-x+15)=0\\\\x=15$

Length = 15 yards

Breadth = (15-15) = 0 yards

Hence, this is the required solution.
