let the consecutive odd numbers be a=x ,b= x+2, c=x+4
formula for a perimeter {a+b+c=105}

x + (x+2) + (x+4) = 105
x+x+x=99
3x=99
x=33

therefore length of each side is
a=33, b=35, c=37

then just plug this into the herrons formula’s

step one:
find half the parimeter (set as variable H impling half perimeter)

step two use:
Find area,
area = squareroot (H (H-a) (H-b) (H-c))

just plug in the numbers and u got the answer…. not doing the calculation cuz the best way to understand math is by doing it urself even if u hate it.
