Answer:
84
Step-by-step explanation:
AC(b)=15
BC(a)=14
AB(c)=?
∆OBC is right angle trangle
In where Angle AOB is right angle
OA (b)=12
OB(p)=5
AB(h)=?
We know that
h^2=p^2+b^2
h^2=5^2+12^2
h^2=25+144
h=√169
h=13=AB
s=(a+b+c)÷2=(14+15+13)÷2=42÷2=21
Area of the∆ ABC=√s(s- a)(s - b)(s - c)
=√21(21-14)(21-15)(21-13)=√3×7×7×6×8
=√3×7×7×2×3×2×2×2
=3×7×2×2
=84
