Find the area of a triangle: base 14 cm, height 5.5 cm.
19.5 cm²
77 cm²
38.5 cm²
770 cm²
i think its either 38.5 or 77

A = bh/2
Which do you think is the correct answer? 
i think its 77 cm because 14 multiplied by 5.5 equals tht

You forgot to divide by 2.
A = bh/2
or
A = (1/2) * b * h 
ok so its 38.5 i get it now thank you so mcuh

You're very welcome.
