Answer: A=448+196pi, P=60+14pi
Step-by-step explanation:
I'm assuming that the figures which appear to be semicircles are semicircles and that the quadrilateral is a rectangle.
The perimeter is 16 + 16 + 28 + (28/2)(pi)= 60+14pi
area is area of rectangle + area of semicircle
= (16)(28)+(pi)(14)(14)=448+196pi
1/9 or 11/100
Hope that helps

Answer:
The answer is the first one.
Answer:
The number is 2
Step-by-step explanation:
Twice a number (z) = 2*z = 2z
Twice a number (z) added to 21 = 2z + 21
9 times the number added to 7 = 9z + 7
9z + 7 = 2z + 21
Subtract 2z form both sides
9z - 2z + 7 = 21
7z + 7 = 21
Subtract 7 from both sides
7z = 21 - 7
7z = 14
Divide both sides by 7
z = 14/7
z = 2
