Question

The perimeter of a triangle is 45 centimeters. find the lengths of its sides if the longest side is 7 centimeters longer than the first shortest side and the remaining side is 2 centimeters longer than the shortest side

Answer 1

x = length of shortest side
Therefore the remaining sides will be x +2 and x + 7

x + x + 2 + x +7 = 45
3x + 9 = 45
3x = 36
x = 12
x + 2 = 14
x + 7 = 19

The sides are 12, 14, and 19 cm. long. Hope this helped!
