In a AABC, if AB +BC =10 cm, BC+ CA= 12 cm, CA+ AB =16 cm, what is the sum of the lengths of its sides (A) 19 cm (B) 17 cm (C) 38 cm (D) 30 cm

Text Solution

Verified by Experts

Given
`AB + BC = 10`
`BC + CA = 12`
`CA + AB = 16`
`2(AB + BC + CA) = 38`
`AB + BC + CA = 19 cm`
so, Perimeter = `19 cm`
