Answer:
The perimeter is 220 , the area should be 100 ,
Step-by-step explanation:The perimeter of the square is 40 because it’s all sides added together & they are all even - The perimeter of a circle is always 360 and this is half of a circle so that is a perimeter of 180; you add that to 40=220. The area is two sides multiplied together=100 for the square. You find the area of the half circle by doing the area of a circle divided by 2.

Therefore she must swim =6.5 miles the seventh week</h2>
Step-by-step explanation:
Given , Rebecca plans to swim an average of 5.5 miles per week.
So, she has swum 2 miles the first week ,7 miles the second week ,6 miles the third week ,9 miles the fourth week ,5 miles the fifth week and 3 miles the sixth week.
Total she has swum =(2+7+6+9+5+3) miles in six week.

To reach her goal she has to swim =(5.5×7)miles= 38.5 miles at the end of seventh week.
Therefore she must swim =(38.5 - 32) miles =6.5 miles the seventh week
