Problema Solution
The perimeter of a Pentagon is 82 units. The second side measures two units more than the first side, while the third side is five units more than the first side. The fourth side is twice the measurement of the first side, While the fifth side is three units less than twice the first side. Find the sides of the Pentagon.
Answer provided by our tutors
Let
x = the length of the first side
2 + x = the length of the second side
x + 5 = the length of the third side
2x = the length of the fourth side
2x - 3 = the length of the fifth side
The perimeter is 82 units means:
x + 2 + x + x + 5 + 2x + 2x - 3 = 82

x = 78/7 untis
x = 11.14 units is the length of the first side approximately
2 + x = 2 + 11.14 = 13.14 units is the length of the second side
x + 5 = 11.14 + 5 = 16.14 units is the length of the third side
2x = 2*11.14 = 22.28 units is the length of the fourth side
2x - 3 = 22.28 - 3 = 19.28 units is the length of the fifth side
