Answer:
a=20cm, b=21 cm and c= 29 cm
then, s=a+b+c/2
s = 20+21+29/2= 35cm
area of triangle=√s(s-a) (s-b) s-c)
=√35(35-20) (35-21) (35-29)
√35×15×14×6
=210 cm²
area of triangle=1/2 × base × height
210cm²=1/2×20×h
210÷10=h
21=h

Answer:
210
Step-by-step explanation:
S = 20+21+29/2
= 35
A =√35(35-20)(35-21)(35-29)
=√35x15x14x6
=√44100
=210
