Answer:
Step-by-step explanation:
We can rewrite the square root of negative 18 as . We can evaluate these two quantities separately. The square root of 18 can be factored to get 3 squared times 2. We can take the 3 out to get
. Now, the square root of negative one can be rewritten as
, so this is equal to
check the picture below.
so the area of the rectangle is x*y.
the area of the triangle is (1/2)(w)(z).
if we subtract the area of the triangle, from the containing rectangle, we're in effect making a whole in the rectangle, as you see there in lower-right corner.
