646,780 times 547,890 is 354,364,294,200.
Answer:

Step-by-step explanation:
see the attached figure to better understand the problem
we know that the area of the room is equal to the area of a rectangle plus the area of a trapezoid
step 1
Find out the area of the rectangle

step 2
Find out the area of the trapezoid

step 3
Sum the areas

substitute the values

Set the radicand in
√
x
−
5
x
-
5
greater than or equal to
0
0
to find where the expression is defined.
x
−
5
≥
0
x
-
5
≥
0
Add
5
5
to both sides of the inequality.
x
≥
5
x
≥
5
The domain is all values of
x
x
that make the expression defined.
