Answer:
48
Step-by-step explanation:
because it gives us the perimeter, we add all the sides
4z-1+4z-1+5z+3+5z+3=166
8z-2+10z+6=166
18z+4=166
18z=162
z=9
side PS is 5z+3
plug in z to get 45+3=48

How to find the area in terms of pi?
Answer: First divide the circumference by Pi to give the diameter of the circle (27 divided by 3.14 = 8.59...). Now halve the diameter to give the radius (8.59 divided by 2 is 4.29...). Now use Pi*r^2 to find the area of the circle (Pi times 4.29^2 = 58.0 cm^2 to 1 decimal place)
