If two sides and Perimeter of a triangle are given, then should we find the answer by dividing the perimeter by 2? for example... (6+7+x) / 2 =18/2 Share with your friends Share 0 Aarushi Mishra answered this Dear studentWhy are you divind by 2. Just add the sides and equate it to perimeterE.g. Let two sides of a triangle be 2 and 13 and its perimeter be 30. Then find the other sideLet the other side be xperimeter of triangle=2+13+x=3015+x=30x=15 If you are using herons formula then you can find semi oerimeter simply by dividing given perimeter by2, but for using formula you need third side too, so you also need to calculate itRegards 1 View Full Answer
