Question

in a triangle ABC if AB + BC equal 10 cm BC + CA = 12 CM CA + AB
equal 16cm what is the parameter

Answer 1

AB+BC=10--------(1)
BC+CA=12--------(2)
CA+AB=16--------(3)

(1)+(2)+(3)
AB+BC+BC+CA+CA+AB=10+12+16
2AB+2BC+2CA=38
2(AB+BC+CA)=38
AB+BC+CA=38/2
AB+BC+CA=19
The perimeter of the triangle ABC=19cm
