anonymous · Answer

and how do I find the area of the triangle

amistre64 · Answer

considering a triangle is half a rectangle .... you might want to divide that in half ...

anonymous · Answer

okay so I multiplied 7cm, 9cm, and 12cm and got 756cm so now I multiply 12cm and 9cm and then what ever that is cut that in half

anonymous · Answer

right

anonymous · Answer

if you are using @amistre64 method. then the area of a rectangle is length*breadth. but in your question only the length is given(12) and not the breadth.

amistre64 · Answer

9 is the "breadth"

anonymous · Answer

so I don't cut the answer in half (12*9)
