Step-by-step explanation:
According to Herons formula
Semiperimeter = a+b+c/2
= 32/2
= 16
now
area = under root
16 ×(16-13)(16-14)×(16-5)
= 16 × 3×2×11
= 48 ×22
=1056(under root)
= 84m^2

Answer:
32.5 m^2
Step-by-step explanation:
a=13m, b=14m, c=5m
Using Heron's formula:
A= sqrt(s(s-a)(s-b)(s-c))
Where: s=(a+b+c )/2
we get
A=1/4* sqrt{-a^4+2(ab)^2+2(ac)^2-b^4+2(bc)^2-c^4}=
1/4*sqrt{-13^4+2*(13*14)^2+2*(13*5)^2-14^4+2*(14*5)^2-5^4}= 32.49615 m^2
