Verified answer

Answer:

Step-by-step explanation:

Area of triangle with sides a, b and c and s=2

a+b+c

​

 is  

s(s−a)(s−b)(s−c)

​

 .

For triangle with sides 24m, 40m and 32m, s=2

24+40+32

​

=48m

Area of the triangle with sides 24m, 40m and 32m =

48(48−24)(48−40)(48−32)

​

=

48×24×8×16

​

=

24×2×24×8×8×2

​

=24×8×2=384m square

Answer:

s=a+b+c/2, 40+24+32/2, 96/2, 48

a=underroot(48-40)(48-24(48-32),. unferroot 8*24*16, underroot 3072, 16 underroot 6
