Question 1031929: The longest side of a triangular sail is 9m long the second side is 1.5m shorter than the longest side the third side is half the length of the longest side what is the perimeter Answer by gargituli(2) (Show Source):
You can put this solution on YOUR website! longest side is 9m
second side is 1.5m shorter than longest side. so length of 2nd side = (9-1.5)m = 7.5m
3rd side is 1/2 of the longest side . so length of 3rd side = 1/2 * 9m = 4.5m
thus, perimeter of the triangle = sum of 3 sides = 9+7.5+4.5 = 21 m
