Answer: 272 square feet

Step-by-step explanation:

We must find the total area of the backyard then subtract the area of the not allowed area from it. Clearly, the length and width of the backyard is 22 and 17ft respectively, so the total area is 22*17=374ft^2.

The restricted space can be seen as two rectangles, both with width 3 and length 17, making their area 2(17*3) =102

374-102= 272

Answer:

So after the second tablet there is 360-mg of drug in the body.

So after the third tablet there is 372-mg of drug in the body.

Step-by-step explanation:

We know that a doctor prescribes a 300-mg antibiotic tablet to be taken every eight hours. Just before each tablet is taken, 20% of the drug remains in the body.

We know that 20%=0.2.

We conclude that after the first pill, 300mg of the drug is in the body.

We have the following formula, to calculate how much mg of the drug is in the body after the second tablet:

$300+20\%\cdot 300=300+0.2\cdot 300=300+60=360$

So after the second tablet there is 360-mg of drug in the body.

We have the following formula, to calculate how much mg of the drug is in the body after the third tablet:

$300+20\%\cdot 360=300+0.2\cdot 360=300+72=372$

So after the third tablet there is 372-mg of drug in the body.
