You need to add 4.5 until you get the closest you can get to 16 with out going over.
If you want to find the product it would be 6x^2-7xy^2+y^4
So first, you would multiply 10 times 10 to get 100 square feet. And since there are 10 exam rooms, you multiply 100 to 10 and you would get 1000. Then to calculate the waiting area, you multiply 20 times 15 to get 300 square feet. Then the office area would be 25 times 20 which is 500. So you would add up 1000+300+500. The answer comes out as 1800 square feet. Hope this helped! Good luck!
Answer:
A. The area is 
B. She needs to cover 1661.9 square feet of tiles for the base of the swimming pool
Step-by-step explanation:
Question A:
Let us assume that the leash is pegged to the ground using a stake. as a result, the dog can move around the stake. The path that the motion of the dog would trace is a circle, and the radius of the circle will be the length of the leash.
Since we know this, we can easily find the area of the circle using 
Area of the circle = 
Question B
Dulce wants to cover the whole surface area of the floor of the circular swimming pool with tiles.
We already know that the swimming pool is circular, hence, the surface area of the base of the swimming pool will be the same as the area of a circle, with the same radius.
The area of the circle can be calculated using 
Area of circle =
