find the area of a triangle using A = 1/2bh where b= 16mm and h= 5mm
This is pretty simple multiplication.
First multiply 1/2 16 to get 8
Next multiply 85 to get 40
So the area of your triangle is 40mm
The formula is right there in the question. Just write '16' in place of 'b' and write '5' in place of 'h', then do the multiplication and you have the area. / / / If you don't get 40 square mm then you have a mistake somewhere.
