Given :
AB = 5cm
AC = 12cm
AD = ?
(ab)^2 + (ac)^2 = 169
BC = 13cm
sol : area of triangle ABC = 1/2 × b × h
= 1/2 × AB × AC
= 1/2 × 5 × 12 = 30cm sq
area of triangle ABC = 1/2 × b × h
                                 = 1/2 × BC × AD
                                 = 1/2 × 13 × AD
30cm sq = AD × 13/2
AD = 60/13 cm
AD = 4.61cm
