Area of 1 exam room = 10 ft. × 10 ft. = 100 ft.²
Area of 10 exam room = 100 ft.² × 10 = 1000 ft.²
Area of waiting room = 20 ft. × 15 ft. = 300 ft.²
Area of office area = 25 ft. × 20 ft. = 500 ft.²
Now,
Total area of the hospital to be replaced = 1000 ft.² + 300 ft.² + 500 ft.² = 1800 ft.²
So all you have to do is look at were the number is is it is in the first spot it is in the tenths place value, second spot hundredth and so
The given expression is:
![16+\frac{r^2}{s^2}](https://tex.z-dn.net/?f=16%2B%5Cfrac%7Br%5E2%7D%7Bs%5E2%7D)
When r=6 and s=2, we need to replace those values into the expression and solve:
![16+\frac{6^2}{2^2}=16+\frac{36}{4}=16+9=25](https://tex.z-dn.net/?f=16%2B%5Cfrac%7B6%5E2%7D%7B2%5E2%7D%3D16%2B%5Cfrac%7B36%7D%7B4%7D%3D16%2B9%3D25)
The answer is a. 25
