Stacy likes to eat pancakes for breakfast. Her utility (happiness) function is u(x) = x 1/3 , where x is the number of pancakes
consumed per week. Suppose Stacy currently consumes 8 pancakes each week. Stacy’s doctor orders her to cut down her pancake consumption by 2 per week. Approximately how much has her happiness changed since she started cutting back on her pancake consumption for a week?
The answer is 4.5 for the side length of the pentagon and 7.5 is the side length for the triangle because 7.5*3(3 sides) = 22.5 and 4.5*5(5 sides)= 22.5. The perimeter is 22.5
