(base times height) divided by 2

No it’s half the base x the height.

1/2 base times height, or 1/2 times a times b times the sin of C, but thats only trig functions.

length times with then half your total

by the way.

why so random?

In candp reply you will see that the answer is half of the base x the height.
Although the other answers above also work out the same, plus the alternative the base x half the height will give the same answer.

The correct answer mathamaticly is :- half the base x the height.

i think mine works as well. take a 6 by 5 triangle, hypotenuse unknown. the square is also 6 by 5, making it 30. but the triangle takes just half of this up, so its 15.

I am not talking about what works and what doesn’t.

I am saying that the proper mathamatical way of finding the area of a triangle is :- half of the base multiplied by it’s height.

Even if it means dropping a purpandicular if neccessary to find it’s height.

Not as you have done, found the area of a rectangle and divided it by two.

When it comes to exams you lose marks for not answering the question correctly.

In every case what you have done gives the correct answer but has not been worked out in the correct manner.

The correct mathamatical equation for the area of a triangle should be (1/2*B)*H

Where B = Base, H = Height, / - divide and * = multiply. Then the part in brackets is worked out first, then multiplied by the height.

The correct way to work out any mathamatical problem is thus :- BOMDAS.
Meaning.
Brackets, first [ ] then ( ).
Of = multiply.
Multiply.
Divide.
Subtract.

Mathamatics is quite an easy subject to understand, as long as the rules are followed.

?

its BIDMAS now

Brackets
Indices
Multiply
Divide
Subtract

oops the example was wrong
i think
but it was still using the height
so it just happened, that the perpendicular was already there
so its the same thing

thx helpe with programming!

basically half the height times base or..
half the base times height or …
base times height divied by two

Half Base x Hight
OR
Half Hight x Base

u really don’t know anything u lot do u let’s be honest on of u talked a bout
pythagros therom which has nothing relevent to the area of a triange oh and about that u don’t need a square for that therom oh and it is not only 1/2 bxh or 1/2hxb that does yes work but also u can do what seemed to be rejected which was bxh divided by 2 so when you ask or answear a question like this check with someone like your teacher (if you go to school) or a work colluge and also this is one of the most simply things in the world wait till u get to trapizems etc

1/2 base x height 3

You TAke either half the base x the height or the base x height divided by 2

all the things u sed are the same answer DUHHHHHHHHHHHH base times hieght divided by 2 and half the base times hright its the same resultttttt

it is base x height divided by 2
