Question

if AB + BC is equals to 15 CM BC + CA is equals to 10 cm and AB+AC is equals to 13 cm then the perimeter of angle abc is​

Answer 1

Answer:

AB + BC = 10 cm …(1)

BC + CA = 12 cm …(2)

CA + AB = 16 cm …(3)

Add (1), (2) and (3) to get

2AB + 2BC + 2CA = 10 + 12 + 16 = 38, or

Hence the perimeter of ABC = AB + BC + CA = 19 cm.

Answer 2

Answer:

AB+BC = 10 cm

BC+CA = 12 cm

CA +AB = 16 cm

Adding we get 2AB + 2BC+2CA = 38 cm

AB+BC+CA = 19 cm

Hence the perimeter of the triangle is 19 cm
