find the area of the triangle whose sides are 42 cm, 34 cm, and 20 cm in length. hence, find the height corresponding to the longest side??

firstly use herons formula under root [s(s-a)(s-b)(s-c)]

s=42/2+34/2+20/2=48

now, root [ 48(48-42)(48-34)(48-20) ]

root [ 48(6)(14)(28) ]

root 112896

sry bt im unable to find after this

hope it helped u
