Question

What is the missing side length of an irregular hexagon with side lengths eleven point seven centimeters, nine point four centimeters, twenty point three centimeters, fifteen centimeters and twenty-one point one centimeters, if the perimeter is equal to the perimeter of a regular pentagon with side length twenty-one centimeters?

Answer 1

Ill give medals!

Answer 2

six point five centimeters

nine point three centimeters

twenty-seven point five centimeters

forty-eight point five centimeters

Answer 3

Well, then regular pentagon has 5 equal sides of 21 cm. So, 21*5=105

Taking the irregular sides of the hexagon: 11.7+9.4+20.3+15+21.1=77.5

105-77.5=27.5
