The lengths in cm of three sides of a triangle are three consecutive odd numbers.
Knowing that the perimeter of the triangle is 40.5 dm, find the length of the longest side of the
triangle.
A.137cm
B.135cm
C.143cm
D.145cm
40.5dm = 405cm
The length of each side averages to : 405 / 3 = 135 ( cm )
The length of the longest side of the triangle is : 135 + 2 = 137 ( cm )
The answer is A.137cm.
