if the measure of the hypotenuse of a right triangle is 15cm if the base of the triangle measures 9cm. what is te area in square centimeters of the triangle??
im just going to give this to you, and hope that you try to understand it 4 square centimeters please explain it and ill try to hellp you understand...
dont get it
thats the area???
yeah, its an area... because an area is two dimensional... do you know what that means?
yes i just get how 4 is the area
what don tyou get?
how the area is 4
oh im sorry, the area isn't 4 square cm, thats the length of the side
oh whats the area
you would use the area for a triangle... which woud be base times height/2 so once you have the base height and hypotenuse, you can work it out right?
for base i have 9 h i have 13 and hypotanuse i have15
is that right
no, how did you get that? and ill tell you where you went wrong
i did a2 +b2 = c2 and inputed numbers
which numbers where?
well i was finding a so b was 9 squared and c was 15 squared
ok, that should have worked, what did you do after you had the numbers in (how did you solve it)?
my anwer for a was 13.1
how did you get that?
by just following it through like nine squared is 81 and fifteen squared is 225
then subtrected 81 from both sides to leave a by its self which was 174 the square root of tht is 13.1
oh ok so look at 225-81 again (its not 174)
ok for area i got 54
yay, but you should say 54 square centimeters... i got 54 square centimeters too
ok thanks
