Answer:

According to Hero's formula,

Area of the triangle, A=s(s−a)(s−b)(s−c)

Where s=2a+b+c=242+34+20=48

Now,

A=48(48−42)(48−34)(48−20)

A=48(6)(14)(28)

A=(6×8)(6)(14)(14×2)

A=14×6×4

A=336cm2

Let the height corresponding to longest side (42cm) is h

Area =21×base×height

21×42×h=336

h=42336×2=16 cm
