Question

In triangle AbC,it is known that AB+BC=10cm,BC+CA=12cm,CA+AB=16cm.Find the perimeter of the triangle.Can we do this without actually finding each side of the triangle,if so find the length of each side.​

Answer 1

Answer:

19 is the required answer

Step-by-step explanation:

Given ,:;

AB + BC = 10CM ---------- I

BC + CA = 12CM ----------II

CA + AB = 16CM ----------III

by adding equation I ii and III

we get,,

2AB + 2BC + 2CA = 38

NOW by taking 2 common from L.H.S WE GET..,

,

2(AB + BC + CA) = 38

THEREFORE

AB + BC + CA = 38/2

AB + BC + CA = 19

THEREFORE PERIMETER OF TRIANGLE ABC

IS 19 RESPECTIVELY

DON'T KNOW CAN WE FIND MWASURES OF ALL SIDES
