Answer:
336 feet²
Step-by-step explanation:
If we have a rectangle that is 30 by 20 feet, that means the area of that rectangle would be 20 × 30 feet squared, which is 600 ft².
If there is a 3 feet sidewalk surrounding it, that means that the end of the sidewalk will extend 3 feet extra around each side of plot. Since there are two ends to one side, that means an extra six feet is added on to each dimension. Therefore, 36 × 26 are the dimensions of the sidewalk+plot. 36 × 26 = 936 ft².
To find the area of the sidewalk itself, we subtract 600 ft² from 936 ft². This gets us with 336 ft².
Hope this helped!

Answer:
Step-by-step explanation:
The percentage of births that occurred among women between the ages of 40 and 42 is 26.41%
<h3>Calculations and Parameters</h3>
First, we would add up the ages of the mothers
27 +98+239+326+389+436+468+490+460+387+286+180+102+48+19+5+1
= 3961
Thus, to find the percentage of births occurring among women between the ages of 40 and 42 was:
102+48=150
3961/150= 26.41%
