Dammit i forgot the formula.
Well, if anyone can solve.
EDIT owate I think i got it
first I must solve for X.
9x7=x
First I must divide 9 on both sides, which will leave me with:
7=9x \
AN DEN I must divide 9 on both sides, which will leave me with:
0.7=x
Now, if the formula for the area of a triangle is LxWxH, i just plug in the info I have obtained.
9x7x0.7=44.1 meters squared.
I'm sure I messed up though.
